Insulating Rim Joists / Sill Plate

Im finishing basement and starting putting foam board on the concrete walls and in the rim joist cavity where I pulled back the loose batt insulation that was there. Iím looking to fill in gaps around the foam board in the rim joist cavity. What should I use for that ?

also, the top of the concrete wall which sticks out past the sill plate is exposed. Should I lay a piece of foam board over it?
