Tom,
I did 3/4" plywood on my last shop walls. More expensive? Yes. Could I put up anything anywhere? Yes. I was going to put frp over about a 1/3 or so to create a wash area, but sold the place before I got too it. But I also had a metal framed structure, so there was good support for the plywood. Given what you've got, I don't think there's going to be a right or wrong answer. Everything will be a trade off in some respect. Plywood is expensive, osb can't really handle moisture, frp is too thin to put up alone, and you can't just leave it bare (though this may be the best choice!).
