Not sure where your getting any of that info.
I'd be using Advantech not plywood, it's stronger, cheaper, no voids in the plys, 50 year warranty.
It's made so there's a built in gap.
Screws will cost 3 times as much, take far longer to install and leave you with raised areas any place the screw goes in.
Constrution adhesive on the joist and 8D ring shanked nails with a framing nailer is the way I'd go.
