Doesn't make sense to use Osmo Polyx oil as the baseline when Osmo Top oil is the slightly friendlier and equally beautiful food-safe version.
Top Oil indeed seems very similar to what I did (hardwax, drying oils, driers) but half of it is still white spirit solvent, which I'm guessing will give it the same smell as Polyx.
The closest thing I found to what I want is Walrus Oil Furniture Butter (https://walrusoil.com/products/furniture-butter) but I didn't know about it at the time.
