Both Watco "Danish Oil" and Waterlox are wiping varnishes. BLO is a drying oil. All of these penetrate and then dry to seal the wood without making for any appreciable sheen in most cases. None of these offer UV protection and are not technically "outdoor" products but you noted your table is in a covered area and not directly exposed to the weather. Bee's Wax doesn't really permit mold/mildew just like raw honey is somewhat of an antiseptic. And as already mentioned, there are outdoor finishing products that would be worthy of consideration, too.
