Derek, Watco danish oil finish might be a good choice here. It comes in clear and different shades like red oak and walnut. You can blend the different shades to get the tone you want. It is very easy to apply and has the advantage of soaking into the wood and when fully dried actually hardens the surface of the wood to a depth of about 1/16". If you get any nicks in the surface you can repair them and reapply the treatment for a perfect match. This produces a nice satin finish. Test it on some scraps of wood before commiting to your cabinet doors.
