Windser plywod and home depot both carry clapmans for the bowl/cutting board wax. I find clapmans is a great product and made in BC. It’s in a little white plastic round container. If you have trouble finding I have some you could use as well as some beeswax if you decide that route. Clapmans is a mix of a few things.
I would would go mineral oil over
coconut oil. You could even just set it in a bath of mineral oil and let it soak for a few minutes.
