New Englander goes to CA // NEED HELP

Hi so ive never been outside the west coast, and now i have a trip coming up in june. I have about a week and it starts off in sacramento, eventually goes to Columbia street historical park, then san francisco.

Are there any must see places in sacramento?

I have the wild sisters bookstore, the mckinley rose garden, and the obo italian restaurant on the itinerary. I really want to see local towns and sweet hidden gems along the way.
