Sure, there are match options outside of WUE - it’s just that WUE can be hard to beat on the affordability front. UH and Iowa State are relatively affordable - the question is whether they’ll be above the curve in terms of desirability vs. cost, relative to your other options. And then you have to assess how much more competitive CS is at each school, vs. the general admissions statistics. You mentioned applying undeclared, which is fine if there’s still a realistic path into CS, but often there isn’t.
If you like Texas as a destination, you might run the NPC for SMU and see if that would be affordable, particularly if you are interested in the more business-y side of CS, since that’s a strength there. Texas-adjacent options would include U of Oklahoma (flagship) and U of Tulsa (private but gives lots of merit).
U of New Mexico hasn’t been mentioned yet - that would likely be very affordable (you’d get the “WUE+” rate), and Albuquerque has a lot to offer.
It’s hard to tell from your list what you are looking for in an environment, other than not-Nevada!
