ACX Fir plywood is good . True Marine Plywood such as Marine Tech is Fir with fewer voids and they throw the glue to it, it has B-grade inner plies. The Marine Tech is more pricey than the standard ACX Fir. The choice depends on your wallet. There are other choices but I would stay away from engineered wood products like OSB or paralam beams. They have their place but plywood is proven to work.
