I bought the 3/4 plywood from Treated lumber outlet, and is nice looking and dry and flat. It is rated for ground contact UC4A. Price was $35.

Some of the new treatments are rated for ground contact.

Treated Lumber outlet, all is ground contact using UC4A micronized copper azole.

Lowes has both ground and non ground contact treated woods.
The structural wood I used from Lowes is EL2 treated and it stabilizes the wood so less likely to warp.
