I would think zig foam would be the better material for you.
Closed cell so it's buoyancy shouldn't change and possibly easier to work with.

Cork can have a significant density which will vary depending on type but it's stable and shouldn't absorb water either.
My guess is the foam should be more buoyant generally but I've never checked that so it's only a guess.
Either should do what you want. I wouldn't worry too much.

If you're going to use a closed cell foam it won't by its very nature absorb your club.

Definitely foam from my experience, cork reduces in buoyancy when glugged , zig type foam doesn't seem to be effected as much if at all !
