My goal is to keep hot/cool air from seeping between floors. Is canned spray foam the way to go? Any recommendations? Pest resistance is a bonus.

Are those water lines? The off-white one looks like an electric cable, which I don’t like (potential for it to rub against the edge of the hole and wear the insulator).
Looks like refrigerant lines to an A/C system to me. Cold line is covered in insulation and hot line is bare. White cable could be power to the unit.
