I am not looking for stellar insulating power, but anything is better than the thin flat conduction plate I have for a wall now.
I would say go with these:

Mine were the 1/2" thick and are a little on the too flexible side.

They should be flexible enough to bend them into the cavities. You do not need glue to hold them in place, just oversize them by 1/4"-1/2" and they will hold themselves in place (I have yet to have a piece fall off my door in the two years since I did mine).

If your door is an 8'x16', you will need 6-8 pieces of foam. Since you are over-sizing the pieces to fit snug, you will end up having a decent bit of scrap leftover. For <$100 and ~2 hours worth of work, I doubt you will find anything better.
