The Bay Area is a 'megalopolis', a big city surrounded by suburbs. 7 million people in all, but it seems smaller because we have more permanent open space than any similarly-sized area. You should aim for 'Somewhere in the Bay Area'.
(BTW the biggest city in the Bay Area is San Jose, NOT SF. SF is hemmed in by water on three sides, mountains on the other, so it can't grow.) If it was me, I'd look for a temporary apartment or room while I got myself established. Spend a few weeks or months driving around the Bay Area to get acquainted with the lay of the land.
Get a job at a hospital. THEN decide what you can afford and where you'd like to live. People will say 'Oh, you should live in Milbrae' or 'Oh, you should live in Campbell' or 'Oh, you should live in San Rafael' or whatever, but the fact is the choices are almost mind-boggling.
Plus it depends on where you work. San Francisco, the city proper, is probably the most expensive and least convenient place. It's crowded and noisy like most cities, but it has some great advantages.
But suburbs run from honest/respectable working class to fancy-schmancy. It will take you a while to get a feel for the place, to learn what you can afford based on what you'll be making (which you probably don't know yet either). So picking a place now would be like throwing a dart at a map!

The East Bay would be suitable. Near Berkeley. San Francisco has about 4% black population.
San Jose is like a small Los Angeles and is 60 miles south, with warm summers and smog and you need a car. If you live in Berkeley or San Fran you don't need a car. San Jose has gotten expensive, not quite as much as S.F. or Berkeley.
But San Jose doesn't have much atmosphere. What exactly do you want to know? I worked in San Jose, went to school and lived in San Fran, and live in the suburbs now.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
