I'd prefer to use something that can be brushed on and soaks in a bit since the top surfaces will probably get scratched over time and I don't want that to be a path for water to soak in if it gets caught in the rain.
Shellac is considered an interior finish so I wouldn't use that. If you are looking for a boat varnish you might consider Epifanes spar varnish. It literally is formulated to use for the deck of a boat. Still if the plywood you used is an interior plywood you will have to touch it up often. Any place where the finish is damaged down tot he wood water will quickly get under the veneer.
