For PAO specifically, also helpful to know where KGO (trio of radio antennas alongside bridges), the Dish / Stanford, Sunken Ship (what it sounds like), the Birdhouse (round structure between Amphitheater and PAO), Amphitheater (as well explained in top comment), 101, and train/auto bridges which often get used as visual landmarks.
For SQL, I can’t really remember too many landmarks that get used often other than Cement Plant (cement plant on the bay slightly past south side of the field) and AT&T (big grey building).
