At the moment I'm leaning towards 3/4x4x8 BC pine plywood. *This will

Is there a different type of plywood or panel I should consider
instead?

Also curious about corrugated plastic roof panels. *Anyone use them for

CDX will last much longer than BC.

Can CDX be cut at the store. *Couple years back I bought some pressure

that be the difference between CDX and ACX?

Yes. CDX is not pressure treated but is rated for exterior use
without ground contact. Since you are covering it with a tarp it
should last quite a while.
Arsenic treated lumber (ACQ) was banned several years back and you
probably will never find it on the shelves anymore. Todays PT lumber
is mostly MCQ (micronized copper) which replaced it's corrosion prone
predecessor.
