Danish oil, then Lee Valley Conservators wax.
When I refinish an old piece I'll strip, light sand, Natural Danish oil, then wax it to fill the micro voids left by the refinishing.
I will never use the dark walnut colour unless I want the Oak to not appear so blonde....Canadian oak isn't as dark as European species.
Unfortunately the old recipe Danish was far better, but it was changed to meet environmental standards.
On some pieces I will finish with clear Minwax finishing paste wax...heavy....buff with a piece of clean old denim, hit it with a heat gun, set on low, and kept moving so not to brand the wood....then while it's still warm, I'll rub on a coat of lemon oil to level the wax ,using my bare hands.
