Fingerboard, fretboard, makes sense.
Two aspects here. Yes, Cocobolo is a very hard and oily wood and I wouldn't worry about wear, unless you put steel roundwounds on it.
Secondly, and more importantly IMO: Over the years I have come to detest anything on a fretless fingerboard other than the plain board itself (with some kind of sidemarkers). No matter how well the neck is crafted, after a few years of playing, weather conditions, neck adjustments etc, the different materials will become noticeable. Even with composite materials, as witnessed by my Zon with fretlines.
My recommendation would be to either go with a blank board, or else cover it with epoxy/polyester.
