The Eastside Sierra around Lee Vining and June Lake and Mammoth and Rock Creek has more climbs and more rock variety than Tuolumne Meadows. Also the higher-elevation crags around Bishop can be cool enough to climb in summer (e.g. Cardinal Pinnacle + Pine Creek). The granite on the Eastside is more "featured" than Tuolumne (and so I think "more fun") and as soon as they open the road, you can drive in to Tuolumne for a day of granite climbing there.
The Eastside also has interesting volcanic rock and now opening some quartzite.
Let's try some statistics here:
https://www.mountainproject.com/v/sierra-eastside/105798288
shows 2000 climbs _outside_ of (higher elevation than) Bishop.
Then we can add about 300 from Bishop to get the total to 2300 routes.
Next let's compare Tuolumne Meadows:

473 routes
Maybe the Eastside Sierra might have enough to keep you busy for a week or two.
Plenty of camping options too.
Airports: Note that Reno (RNO) or Las Vegas (LAS) might be closer to the Eastside than the big-city California airports. Also consider MMH.
. . . (Too bad you already purchased tickets for SFO -- I used to make that mistake too).
