I applaud you looking into it this early but I think things will be very different from an admissions (for example, how the SAT/ACT will be used) perspective when you apply. It is simply too early to begin narrowing your focus.
CP Pomona, Chico and Sonoma are 3 relatively academically accessible CSUs with good education AND student experience. My son studies under a WUE at Fort Lewis in Durango Co, and loves it. Others to consider, Co State, NAU. UNR, and Boise State.
I should add, the CSUs are sticklers for their A-G courses, in our experience, the other states had more flexibility.
Do your best and check back an 18 months.
