I would make the comparison to "Upstate New York" [0]. I like this Wikipedia article more than the one for Northern California because it admits that "there is no clear or official boundary between Upstate New York and Downstate New York".
The same is true for Northern and Southern California. There's no official distinction. Calling the Bay Area part of Northern California places too much emphasis on the Los Angeles area. By analogy, saying that "North" begins at the Transverse Ranges is like saying that "Upstate" begins at Yonkers. Ridiculous.

Yeah, we are in NorCal for all practical purposes; actual geography be damned.
The Bay Area is definitely not within Central California, taken as a sociogeographic term. The Central California Coast is the coastal region between roughly Santa Barbara and Point Lobos, centered on SLO. There is also another inland definition of Central California: https://en.wikipedia.org/wiki/Central_California
