Downtown Austin already feels like a mini California. Trans and gays, rainbow colored hair, the works. They even had a huge gay parade recently.
I would not move to Austin unless you are a tech worker tied to your Big Tech job, in which case Austin is still less crazy, less crowded, and more conservative than the Bay Area.
And regarding the OP, I'd rank his finalists as follows:
1. Dallas
2. Tampa
3. Houston
While Dallas may not feel stereotypically a part of Texas, it is probably one of the best choices in the US as far as major cities go. The mainstream social scenes are majority white and has a rather upscale feel throughout. It has good business networking and dating scenes if you are into that. The overall upscale/pretentious social scene does have the capability to bind people from different walks of life together (same thing can't be said of many other cities). Generally, it is cleaner, safer, and nicer than most major cities its size.
Economically, it specializes in corporate relocations from established companies in blue states or even overseas. The corporations do range from small businesses to Fortune 100 multinationals and everything in between, with most sectors fairly well represented. However, it doesn't have a particular economic sector which it is a leader in.
Houston has very strong oil&gas and biotech/healthcare sectors. I've heard mixed reviews about the social scene but among these 3 cities, it does have the largest international scene and most international flights. It has less crime, is a lot less white, and more cliquish than Dallas. While it is a leader in biotech and oil&gas, its economic profile isn't as well-rounded as that of Dallas. Like Dallas, I doubt Houston feels stereotypically Texan either.
I don't know much about Tampa, but it seems to have better reviews than Houston does. It too is a sizable city. One major downside of Tampa is that it lacks a major airline hub unlike Dallas and Houston but shouldn't be a problem if you are not a frequent traveler.
