Commuting is not possible in these circumstances (80 miles in SoCal for a D1 athlete) so the real choices are CPP, CSUF, Cal, and the un-named schools (please do give their names and net cost, too, so that we can evaluate them against CPP and CSUF.)
Have you checked into Blue&Gold scholarships and other UC scholarships?
What’s your parental contribution?
Does your son currently have a job, can he work fulltime in the summer?
What major is your son considering? I’d consider CPP better than CSUF, but it may depend on major.
As an athlete, it’s clear running for Cal is going to mean a lot more to him and his life than running for a CSU.
The academics will be more demanding at Cal, for sure - does he feel that he could handle it (what’s his curriculum rigor, has he taken mostly honors/AP classes?)
