Tung oil, which is nothing but a varnish/boild linseed oil mix with drying agents in most cases. Does not give wood a protective hard coating, and it wont hold up long on a fretless application, especially on maple.
Epoxy is a royal pain, it takes forever to dry, and in my experience will seep under the tape used to make a dam on the finger board.
CA glue applied in thin coats with a rag would probably be the easiest finish. Just be sure to wear the correct gloves and a good respirator, as those vapors are pretty nasty.
