The typical SFO VFR Class B Clearance for VFR traffic traveling Northwest or Southeast bound is to stay west and south of Hwy 101 at or below 2000 ft. MSL. At this altitude, we're talking to SFO Tower. Above 2,500 ft. to 3,000 ft. we usually talk to NORCAL Approach.
Hwy 101 is the road that circles the left of the field in the top two photos.

The 28s are the runways running lower right to left.
The type of small aircraft is still in question. I have a Helio Courier, however, SFO tower often refers to me as a Cessna since it's the typical small high wing aircraft. Aeroncas and Helio Couriers are not as well known, but they both also have high wings.
When I transit the area, I'm ready for anything. I've been asked to descend to 1,500 ft. for opposing VFR traffic, or to do a 720 so that traffic can clear the 28s, or turn left and cross mid field passing behind the departing heavy.
The trick is to listen carefully and obey instantly.
The system usually works well.
