I would use fire block since normal expanding foam is flammable. If I could get behind it, I would see if the hole was excessively large and if so, cut a piece of OSB to fit the space with a hole the correct size in it. Then I would bisect the piece of OSB (making sure to bisect the hole) so that I would be able to get it around the cables and refrigerant line. If the hole isn’t excessively large, fire stop caulk the penetration and insulate the best you can.
