While the UC’s have one shared application, so “shotgunning” UC campuses is no more work than applying to just one, paying upwards of 70K/year to attend Merced OOS in search of the “California Lifestyle” would be a mistake IMHO. It’s solid academically, but the location is not near the beach, nor near any of the major cities. You might as well go to UNR for less than half the cost. Riverside is also questionable as a bastion of the “California lifestyle.” Both are good schools that many CA students have to be convinced to take seriously, and I think they should, but they’re not paying 80K/year to go there.
For an OOS student, I’d consider CSU’s like Cal Poly, SDSU, and maybe SJSU, as parentkeith said… and also private schools like Santa Clara and LMU. Your strong SAT will help you with both admission and merit at the privates, whereas the CA publics are test blind. You might have a look at Harvey Mudd - it’s a reach, and you would have to like the broad/deep STEM core that’s required, but it’s a top CS school, and your stats are above their median, and the Claremont Consortium is definitely a California experience.
You mentioned liking the Southwest - schools like U of Arizona, ASU (Barrett Honors), and U of Utah (Honors College) are all strong in CS and likely a great value with the merit you’d receive (and Utah’s option to convert to in-state after the first year).
If you’re considering enduring the upper midwest cold to be close to family there, consider the Minnesota schools as well. U of Minnesota Morris is a well-regarded public LAC with strong CS (and the option of internal transfer to the Twin Cities flagship campus if you want the large-school experience as well), and a huge bargain (OOS sticker price <25K/year)… and Morris is less than a two hour drive from ND State. UMinn Twin Cities itself is a very strong school for CS, and within an hour’s radius from there, there’s Macalester, St. Olaf, and Carleton.
You didn’t mention National Merit - how did the PSAT go for you? There are some great warm-weather CS schools that would give you a full ride if you’re NMF - UT Dallas and UCF, for example.
You like Purdue enough to apply ED? Consider Virginia Tech also. And GT.
You like CWRU? Many students who like Case also like Pitt, which has rolling admissions - apply in August and you could have a very early acceptance in your pocket, which would spare you wasting time on anyplace you like less than Pitt.
I think you need a “divergent” phase of exploring a lot more options before you narrow down your list. Luckily you still have time for this! You have a strong record and could get into many great schools.
