Another option would be to buy at home depot or lowes a short length of dowel rods the same size or slightly larger and put that into the holes. These places also sell iron on veneer so pick the veneer that best matches the area, they typically have maple, red oak, oak, and walnut. Make sure you install the dowel plugs deep enough so that you can put the veneer patches on and do some light sanding to get the correct finish. Then on the inside of the cabinet you can just cut the excess off and stain with a dark walnut.
