My 2 cents - if the wood surface has a finish on it - lacquer, varnish, shellac, etc. - the products above aren't doing anything with respect to the wood. They sit on the surface and evaporate. The finish is doing what it is meant to do - protect the wood structure underneath. Applying these products might make the furniture etc look nice (temporary) - but that's all it is doing.

Exceptions to the above - true "oil" finishes - such as mineral oil on a butcher block for example. "Tung oil" products typically have a hardening agent of some sort so it's not truly only oil. The wax mentioned above likely has some solvent and component that truly does soak in the surface.
