I would have to go with the plywood option too. The edges aren't as pretty but you can get thin laminate to take care of that. Birch is nice, oak, poplar, some Home depots are even stocking maple now. I would also go with 3/4 inch...nice and strong. Cherry would definitely be more expensive than oak and not as easy to come buy...pine, birch, oak, poplar, maple are all available at Lowes or Home Depot, even in smaller 2'x4' cuts. Happy building.
