A friend of mine teaches at Emporia State University in Emporia, Kansas. I just checked their website and you actually barely miss the eligibility requirements for a scholarship - and your ACT score surpasses them, actually. So, you should have no problem being accepted. Furthermore, it’s a medium-sized school with only about +/- 5k students.
It is also very affordable - around 8k tuition for OOS students.
Here is their info about admissions. It appears you will be accepted with a 2.0, 21 ACT, and if you have the high-school class requirements.

I would also look at other 2nd and 3rd tier “directional” colleges and universities in your state and others, i.e., NOT the main campus or “flagship”. Examples : Indiana State in Terre Haute, Iowa State in Ames Iowa, Western Illinois U in Macomb IL (that would be another good option for you, I think)… I’m only familiar with upper Midwest schools, but you get the idea. I’m sure there are similar ones in OK and nearby states. Again, the Kansas public universities look like they’re easy to get into. In fact, you may be near the top middle of the applicant pool.
Good luck!
