Welcome! We are in the Peninsula and have lived pretty much everywhere around the Bay between the two of us, with exception of the far-flung corners. One toddler and one (hopefully, knock on wood) on the way. Let us know if you have any specific questions.
I find I have to take it all in here, treasure the good bits, and ignore all the bits that just aren't relevant to our cost of living situation. Every time someone throws out advice of "move to a LCOL area!" I just internally shake my head and think "but then I'd have to live in a LCOL area, and who wants that? I'd rather keep working." :)
