If you’re looking for local schooling shows, Springdown still does 4 a year in PV. There are several in the east bay, the Tri Valley series at Maddox Farm and I think Cerra Vista still holds them. Metro Horsemens Association has some too. Then South Bay Ranch down south has an English series, I think also run by one of the Horsemens Associations.
Further south is a new schooling series, here’s their link https://www.davinciequestrian.com/central-coast-show-series
More options than you think if you know where to look!
