We are using Tung oil to finish a cabinet made using beech plywood.
It is the type that has a very thin layer of wood followed with a
layer of MDF to make it smooth. It looks great for a surface, but it
seems like the is next to nothing for penetration of the finish. We
hve used tung oil in the past and been very happy with it but that was
on the "old style" plywood. I would like to know what others have done
with this type of plywood.

....sounds like you've got cabinet-grade ply. Let 'er rip.
You should be able to stain and finish with any standard product...
