I wouldn’t use pressure treated inside of your panel for the same reason it’s banned for interior use. It’s toxic in contained areas.

Panels and burbs came with plywood not planks so I would look for marine grade plywood available in most lumber stores as special order. You can even order it from the big box stores. Once sealed, it will last a long time.
