Sorry, i can't help you. I put both my sheds on slabs, and will never worry about having to replace the floors or dealing with them sagging.

16" centers would have been preferrable.
But 3/4" exterior plywood should do fine.

You should use pressure treated wood for the joists/stringers and exterior grade plywood for the floor. I would also use pier blocks instead of concrete block. I like to dig a shallow hole (3"-4") about twice the size of the pier block and puddle a concrete base for the pier.

Also make sure that you;

1. Have at least 8" between any earth and wood,

2. Provide adequate ventilation of the space under the floor,

3. Grade the area to ensure that water doesn't collect under the shed.

There is pressure-treated plywood. It's used to build wooden basements.
