Welcome to "treen" -- the brit term for wooden ware used in the kitchen and home. Plates, cups, goblets, scoops, and small containers --
People have been using wooden ware for centuries and it comes with some maintenance. Oils and waxes are easy to maintain. Film surfaces generally "go south" and are hard to maintain/resurface once cracks or chips happen.
Wooden ware does not do dishwasher!!! Death and distruction of wooden items is assured with dishwashers and time. Hand washing and occasional refreshing of an oil/wax surface is practical. Dishwashers combine heat, water, pressure, and some pretty agressive chemicals to get things clean, and those are not good things for wood and wood finishes.
Your finish is going to be a balance on use, durability, and repair/refinish. Plexi finishes are going to provide excellent durability of occasional use and hand cleaning. Once it starts to fail, it will need a refinsh. It can be viewed as a heavy duty lacquer style film finish with better durability.
Every day use suggests the waxes and polmerizing oils -- think Mahoney Walnut Oil or paraffin as good durable waxes. (Sorry -- but while Beeswax is traditional, it is really a set of esters that tend to attract water -- and I used to be a beekeeper and like it)
Suggest you stay away from CA as it breaks down with heat (about 190 or so) and any treen is likely to get hot sometime in its life. One oops with the dishwasher is a serious problem with CA glue (been there and done that -- the T-Shirt did not fit).
If you have open grained walnut, leave some meat in the goblet section and think about soaking it in hot wax to fill the pores. (And do avoid red oaks -- they will leak!!)
