Okay, so that brings things much more into focus.
There are good CSU options for you academically but they’re not going to be financially advantageous. You must be in the ELC category of guaranteed admission to a UC campus, with your GPA, and so whatever UC campus you like best of the ones you can get into is going to set the bar financially; and then you can look at private colleges/U’s through the lens of cost and value relative to that UC baseline. (Or, the baseline of commuting from home to SDSU.)
Right now your SAT score is the weakest part of your credentials. It’s not terrible, but it’s not in line with your GPA and course rigor. Your EC’s seem strong enough to support your application to well-matched schools, but not strong enough to raise the level of what a well-matched school is, if that makes sense. So I think you may be able to do a bit better with test-optional schools, but I think you would need a more striking EC profile to get into the very most competitive ones (like Bowdoin or UChicago), because withholding test scores just means the rest of your profile needs to be extra-amazing. You’re a terrific candidate for Whitman, though (and yes, flying there from San Diego is a 5-hour trip with a change at SeaTac, but still shorter elapsed time than getting to/from the east coast), and I don’t think you’d be out of the running at Pitzer, which is the only test-optional/full-need-met school in CA. Here’s the list of all the ones I know of. (Leaving the women’s colleges for the benefit of female students who may reference the thread.)
UChicago (IL)
Bowdoin College (ME)
Smith College (MA) (women only)
Wesleyan University (CT)
Bates College (ME)
Bryn Mawr (PA) (women only)
College of the Holy Cross (MA)
Pitzer College (CA)
Mount Holyoke College (MA) (women only)
Skidmore College (NY)
Trinity College (CT)
Union College (NY)
Dickinson College (PA)
Whitman College (WA)
Franklin and Marshall College (PA)
Connecticut College (CT)
Wake Forest University (NC)
Of these, only UChicago, Wesleyan, and Holy Cross commit to no-loan aid for low-income students.
You might also want to look at some full-need-met schools that aren’t test-optional but are a little less reachy stats-wise, such as Occidental (CA), Macalester (MN), St. Olaf (MN), Oberlin (OH), and Union (NY).
Hopefully it’s not too big a project to go down the list and sift out the ones that are 1) better financially than UC, 2) realistic admits and 3) appealing enough to consider in terms of location and other attributes. They’re all excellent schools in terms of quality of education, and they’re all primarily-residential campuses.
