Sonoma would certainly be better than East Bay. The nice thing for you is that you don't need to decide right now. I'd apply to Sac, SF, Sonoma, Chico and maybe a couple of other Cal States. Get admission packets then figure out your next steps.
Again, housing near the Central Valley Cal States is around $500 a month for your own room in a house or apartment that is a short bike ride from campus, perhaps another $400 for food, etc.and, frankly, you have to eat no matter where you are. If you are honest about the true cost of driving (gas, tires, oil changes, etc), tolls, parking, etc, it is easily higher than $500 a month, commuting really is a false economy. Now, if your family home is closer, that's a different story.
Assuming you've calculated your GPA correctly - note, UC GPA is capped at about 4.4.... you are a very competitive applicant for all the UCs. Note though, they can be finicky so, apply broadly. I"d add a couple of privates, maybe LMU, USD and Santa Clara would be happy to have you. Why not also apply to an elite school like Stanford/Harvard/CalTech or one the Claremont McKenna schools?
The list of WUE schools with a view of the Pacific from campus AND offer a 'college experience' is SHORT. Just Humboldt, but, if you think Chico is isolated, try making the drive to Arcata.... Channel Islands is really close but, it doesn't yet have much of a buzz around it. Monterrey doesn't participate in WUE anymore.
You really should visit all the campuses before getting your heart set on one vs the other.
