: So basically, plywood does not expand as much as solid wood?

For what it is worth, plywood will shrink in thickness.

Try dovetailing in ply and observe the long-term effect in which the pins
and tail ends start to stand a little proud. A reason why one shouldn't
veneer straight on top of plywood.

However this should not greatly matter in the type of project envisaged.
