Which glue is best for this jointing project? PVA, urethane, catalyzed
epoxy, etc? I want the board to be strong as it will be used for a small

All of those glues are stronger than the wood.

I do my glue-ups with standard yellow glue, including doors that get
milled and large table tops, and I've never had a glue failure.
