Hmmm...

In an arranged marriage, which is what the girls basically have, feelings and personalities are optional extras; they're getting married because their families see some benefit to be made from tying the two families together in unity.
True. Eastern views of marriage has shifted over the last twenty or so years, but in the timeframe that Ranma takes place in, the Japanese still had a more "business-like" way of looking at arranging marriages. Marrying for love was, and still is to a certain extent, considered a bad reason to tie the knot.

Superior? In what way? You said it yourself: "... they're getting married because their families see some benefit to be made from tying the two families together in unity".
This would mean that Ranma and the Soatomes as a whole would have to get some benefit from such an arrangement. Unfortunately, they won't. There would be no mutual benefit involved; it would be all one sided in the Amazons favor.
From the Joketsuzoku point of view, they would get all the benefits without sacrificing much. Remember: Teaching Ranma Amazon techniques was more a means to and end and not the goal. The goal being getting Ranma to consummate the marriage between Shampoo and himself and going back to the village and start raising little Amazons.
Ranma moving to China, siring and raising little Amazons would not benefit the Soatomes in any way - even if they throw in training Ranma in every martial art technique they have. It still would mostly benefit only the Amazons.

Undeniably? That is a real stretch and a highly questionable conclusion and is based solely on opinion without any shred of support from the manga.
However, if you want to take this realistically, you must consider the isolation and population size of the Joketsuzoku village. It is not very big and therefore Shampoo will most likely be genetically inferior to any of the other girls because of the limited gene pool in which she is derived from. The chances of her being the product of inbreeding and ancestral multiple inbreeding is very high. This has always been a real problem with isolated tribes across the world.

This is a matter up to debate and a separate issue, however I'd like to point out toward the end of the manga (which is
the canon) - Akane was more than capable than holding her own against opponents that were way stronger than Shampoo. In terms of raw power, Akane is more than a match for Shampoo; in terms of training, Shampoo has it all over Akane. There is good groundwork laid in the manga that with equal time and training Akane would obviously be equal or better fighter. The real difference between them and the only edge that Shampoo has over Akane is the amount of training she has had, coupled with the fact that Shampoo has no problems with killing anyone.
But really, that is all irrelevant to the central problem here.
The problem with an "Amazon arrangement" is: While it would greatly benefit the Joketsuzoku by introducing fresh genes into their limited gene pool, Ranma and his family would get very little, if anything, in return. Grandkids? Techniques that they cannot profit from? Insuring their retirement? Nope. Nothing really - at least nothing that they can really take with them and benefit from in a short term or long term way.
Therefore it would be a bad business deal for the Soatomes and doubtful that they would agree to it.

This is very highly inaccurate and completely unsupported. I don't mean to sound condescending, but there is no way that anyone who has even read one volume of the manga could come to this conculsion. I am a bit baffled by this statement as I will detail my bafflement in the following.

Contrast to what you claim, the reality is that the Tendos have an well known, established and well maintained training hall all set up for a new teacher and master to take over.
The part of no students is a guess on your part that is not supported one way or another in the manga. Since the story centered around Ranma and company, how Soun made money for the household was not important enough to detail, the best that we can hope for is educated guesses. (Sorry Nabiki fans, but she is the biggest drain and proven danger to the household budget, far from the breadwinner that many fics like to show.)
There are a few, rare panels in the manga that does hint at Soun having some sort of job or employment, but not exactly what - it sometimes involves travel. The natural assumption would be that he runs the dojo. If that were the case, then he must have students. Adding to the theory that there are students is the fact that the dojo is well known - far and wide; well known enough that Soun gets calls to aid in something or other from time to time (which consequently, involves travel). Though this is not a "smoking gun" this does suggest that the dojo is functioning at some level and there might be students.
Like I said, this is mostly educated guesses based on razor thin evidence, but at least it is razor thin evidence can be somewhat supported by what is shown and inferred by the manga. So while this is still conjecture, it is less so than your statement.
As far as Akane's skill level goes: She is skilled well above the average martial artist, but not on the same level as Ranma. But Akane's - or any of the other Tendo daughters - skill is irrelevant for an arrangement. As I pointed out above: The Japanese point of view towards marriage is more business-like. The Soatomes are providing a teacher and the Tendos are providing something equally important: An established, well known place to teach.
As far as the other suitors go, seriously look at them: One wants Ranma to live in her "dream life", with him at her side running a restaurant or other food service place. Another wants to drag him back to some back-water village far from his home, family and country and start having prize babies with him. The last suitor, just wants him because she feels the need to be loved by someone. True, this is a rough over-summarization of what the girls have to offer, but basically that is the core of it.
In comparison, the Tendos have a way more mutually beneficial deal to offer the Soatomes than the Amazons do.
It is fairly clear and well supported by the manga, and from the Japanese mindset, that the Soatome/Tendo agreement is the most beneficial to both families. The Tendos would get the next generation master for the dojo, the Soatomes would get a place for their art to be taught and passed on and both elders of the families would have their retirement secured. I know that sounds selfish, but from a cultural aspect (at least in the timeframe of Ranma 1/2 took place in) this sort of thing was fairly common and it was expected that the children take care of the elders in their old age.
I cannot think of any other arrangement that would benefit both parties like the Soatome/Tendo one.
