One thing about thicker molds that I have ran into is you have to reposition the rim in the mold through various elements of the build. Particularly when sanding the rims for their radius. On rims that cover nearly the whole side they hit the dish.

IME 2 1/4" thick is thick enough to hold the rim correctly, but thin enough to....work around without having to move the rims in the mold until the box is closed.

3 layers of good quality-void free 3/4" ply (2 1/4") is pretty much standard.
