Best finish for wood slabs?

I just finished a live edge coffee table, I’ll probably post it later today, and the finish I used gave we all the character I could want out of the wood.
I did a 1:1:1 mix of polyurethane, boiled linseed oil, and mineral spirits. It’s a wipe-on mix, so you flood the surface and wipe it off 15-20 minutes later with a blue shop rag. Watch those cracks if you use this technique, they’ll push out finish as they dry so they may need additional wiping for up to an hour after every coat.
Since it was a tabletop and this is a thin finish method, I took about 12 coats for the tabletop. Around 8 or so the grain really started to pop. After this, I finished it with paste wax which gives it a medium to high gloss finish.
As with any finish, buff out with 0000 steel wool between coats.
