Wall cavity with a *LOT* of CAT5E wires

So I have a wall cavity where about 13 runs of CAT5E terminate behind a double gang box, and one in a single gang box. I'm getting spray foam done tomorrow. Do I ask them to fill in the cavity? Or do I attempt to do fiberglass like the rest of the walls?

If I go with fiberglass, how do I get the fiberglass in behind the wires? They are *crammed* in there. Any advice is appreciated.

I wouldn't use spray foam. I would still want access to the cables.

Not a insulation guy but my guess is if you never want to access those wires than foam. otherwise I would not worry about going under the wires just lay the fiberglass on top.

Decided to do it fiberglass, although when the guy came he sprayed it anyway, I had to pull all the foam out before it hardened. LOL!
