Does it have some vents? Soffit? In the gables or a ridge vent? Venting is key to avoiding condensation. The ones for sale around here generally have venting. Plywood floor is fine. Mine has one and no condensation problems. Of course climate is probably a factor too.
Doubt it will make a lot of difference. If you have no base now, you want a plastic sheet for moisture barrier, then plywood.
Or have it elevated on pressure treated supports so that the floor is off the ground. Which I think is better, because even with plastic, isn't water going to get between the floor and the plastic anyway and stay trapped there? I have a base of washed stone, then pressure treated wood that's couple inches thick that supports it and keeps it off the ground.
Help is here - never worry .
Most people think that moisture comes from the ground - when it's actually in the air - all around us. John T.

We had a platform built, about 4 inches from the ground, to set the shed on. We didn't use treated plywood because of the toxins it can emit, but we did seal the plywood on all sides. No sweating.
Today's pressure treated lumber and steel don't mix.

That is a great link with very useful information, thanks!

Pressure treated lumber is nasty stuff.
I built a deck 8 years ago and all the "special coated deck screws" rusted through, had to totally rebuild it last spring with stainless hardware.
Sounds painful. Sorry you went through all that. The stainless hardware must be obscenely expensive?
