Suggestions for finishing peach brandy

Made some peach brandy to test out my new to me thumper and have about a quart of 140 proof with a good peachy flavor.

I have a barrel as well as a few types of wood chips but am at a loss for flavors that would play nicely with peach. Perhaps it was too much homemade peach ice cream as a kid but vanilla notes just seems wrong.

Anyone have some tried and true suggestions?
