I would also say both oak and ash are the best options and also very light in color. Ash will probably have a tighter grain than oak. Oak will probably look nicer if some wear/tear does occur. But both are often used for utilitarian needs. ash: tool handles, baseball bats, etc. oak: ships, etc.

Probably a lacquer or Shellac that will create a durable finish over the wood

I would say a hardwood (oak?) Or corian. Stainless steel is probably the lowest maintenance (think commercial kitchen) but probably the most limiting style wise
