By % residential, i mean the concentration of students living on or very near campus. Some, like Cal Poly SLO, Chico and Sonoma have high density of students who walk/skateboard/bike to class. If you see someone 18-22 on town, they are probably a fellow student.
Others like LA, Sac, San Jose and SF are surrounded by major metro areas so, most of the student body commutes. Campus can get pretty quiet off hours, it can be harder to make friends, etc.Conversely, you are in a metro area - with employment, entertainment and distraction opportunities,
One isn’t better than the other - they just offer the student a very different experience.
As far as CSUs - Based on your interests and qualifications, Long Beach, Monterrey, Channel Islands, SF San Marcos, Humboldt and Sonoma would be worth a look.
I also think you have an outside shot at UCSC but, with a 3.3 UCGPA, I wouldn’t count on it.
Privates like USD and LMU are also options - but could be expensive.
Take a couple of official tours while school is in session. Pick a varying size and environment. They will help you categorize schools you haven’t toured.
Good luck.
