Hardwood plywood is a great material to use. The most flexible type is birch plywood, because it is very light color, and has very subtle grain, which doesn't interfere with staining it. Oak is possibly an even better choice, if you like the open grain of oak. It also stains very well. Except for those two, hardwood plywood can be very expensive, but can look absolutely great. I once used mahogany plywood to make a large desk that fit inside a closet as an "office", that was as beautiful as anything I ever made. But, it was also very expensive. You do need a good plywood store to find those expensive plywood types, which I do have.
