The crawl space under my house is insulated with a single layer 3.5 inches of fiberglass between the joists. I want to upgrade the insulation. I was thinking of rigid foam bonded to foundation walls and across the joists. Any suggestions?

Waht you suggest is one option but you may be better off insulating the walls and floor fo the crawlspace with foam to achieve and even greater insulating capacity.
Homebild, how owuld you suggest insulating the cinder block that make the walls of the crawl space? I know you said foam, but what type?
