I have to edit that ~
Just checked the 3/4" ply would has a .94 R-value , that's no good. Rigid blue is the way to go. For sure for sure.
Yeah, foam is a kick-*** value in a situation like this, you get some structure and some decent R-value too.

They have 2" thick foil-covered stuff at the box-stores around here for around $23 a sheet. The R value is superior with the mylar foil, but it's Expanded Polystyrene (EPS) foam so it's not as strong as that blue or pink Extruded Polystyrene (XPS).

The foil tape is a a good idea for the joints.

The R-30 fiberglass rolls meant for attics are 25' long and do not have a vapor barrier. That's about the best value per square foot and R-value you can get from a hardware store. For someone without a bunch of leftover glass, it would be a great way to get enough to stuff an enclosure or box around a water tank.
