I don't know where you come up with such an outlandish statement, but you are 100% WRONG. Marine grade plywood has no additional treatments to prevent decay/rot CLICKY.
For the OP I agree either MDO, HDO or pressure treated could be options with the first probably the best overall.

Use that, it's probably MDO (Medium Density Overlay) plywood.
Yes, MDO plywood is what you want.
As a boatbuilder, I can tell you that marine plywood is so graded because of the greater number of plies used and the absence of voids in internal plies. It is not usually rot-resistant wood -- it depends on the building techniques and barrier coatings to keep it from rotting.
MDO is a better choice for your job.
