Toupret makes a filler for this purpose. Fibacryl. I don't like expanding foam much because it is difficult to remove it from anything you didn't want it on and hard to store and use the cans more than once so there's a lot of waste involved.
Fibacryl on the other hand will shrink in certain gaps. You can supplement it with the gap filling things :-

which can be kept in the tool box for years without going off.
