Derek, sounds like a 21st century French Polish. The OP is fortunate in that the cabinet work is in fact veneered and not the photo printed stuff on modern vans. The difficult thing is every trace of the original finish would need to be removed to get an even finish. For that an abrasive route is not the best option and I would go for a chemical stripper followed by scothbrite as opposed to wire wool.
When I've tackled refinishing of an old surface I've usually gone down the Danish oil route unless the piece has been originally French polished and still has value. In these cases I've cleaned the surfaces back with mets, no abrasives, then given a couple of rag coats of French polish and sometimes a light waxing.

Derek,
no problem. The great thing about a forum is we get get a variety of different opinion, tastes and methods. The more options out there to choose from the better.
I'd forgotten about the Osmo Oil. I'd tried the clear and a client wanted a whitewash Scandi effect on something so I tried the white one. It gave a nice effect.
IKEA do something similar but I've not had success with it.

Compressor driven spray gun and a 50-50 mix of old engine oil and creosote. I could do the underside of his van while I'm at it.

It could also be used to give a good spray tan.
