I'd be inclined to build lighter than specified with the better plywood. You'll save money if you minimize the sheathing. Like use 2 ounce glass on the topsides, since you are only really trying to prevent checking.
That said, you can probably use about any plywood as long as your glass holds up.
Here is a question. Home depot has a premium ac
plywood called Araucoply it is made from radiata pine it has a nice face
few or small voids [ I think they could be filled with "peanut
butter"} I've read that radiata pine has low rot resistance, but my boat will
be glassed 2 sides, painted light grey and live on a trailer most of
it's life. I also have a ton of red oak for for the solid wood The ac
plywood is 25 bucks a sheet, marine in Phoenix is 66 bucks for3/4.. Do you
think it would hold up? I hope so,cause I have bad case of T.W.M.B. aka
as the working man's blues. ALL THE BEST ; Patrick
