I've been watching this video - What Kind of Finish Should You Use? | WOOD FINISHING BASICS
In this video, Steve is saying that oil doesn't offer much protection, less than Watco mix oil/poly. What about this kind of finish (Kunos from Livos)? It is all natural linseed oil based but has a bunch of wax mixture in it (https://livos.com/images/documentation/en-us/technicalDataSheets/TDS_243_KUNOS_Countertop-Oil.pdf
). I think this would offer a better protection than normal oil finishes.
