Danish oil or tung oil. I use Liebron. Penetrates well.Gives a good satin sheen finish and doesn't sit on the surface. Excess can easily be wiped off and it's water resistant.
Be very careful with equipment used to apply some of the Danish/Tung oil products. If using a cloth do not screw it up tight when you have finished as they have been known to self ignite. I always lay them out flat to dry in an area where they can cause no harm. Don't let this put you off, you can get really good results. Although for walnut I try to use walnut oil.
🤔 ...... I use parker hale walnut oil just pour on to your fingers and rub in takes a bit effort but well worth it i oil mine twice a year
