Polyurethane glue (Gorilla and others) is absolutely water resistant.
Messy but effective.
I have glued treated boards together that the glue held up and the boards roted away, ground contact over 5 to 10 yrs.
heheheheh, I know that's a fact!
I was working with Gorilla glue on a rainy day, going up and down a muddy ladder, and the little bit of glue on my fingers picked up the mud from the ladder.... It took three or four days to wash off...
Gorilla glue is good stuff, but if it's not necessary, I avoid it.
I like Titebond 3... But Titebond 2 is better when you want a longer drying time.... on the bottle, #2 calls for one hour clamp time, and #3 calls for thirty minutes.
I've been using #3 for as long as it's been out. It's good stuff when it suits the job. It sands well too.
One other difference.. on the label...
#2 says "water resistant"
#3 says "waterproof"
But, for an end grain cutting board, I think the elasticity is the most important thing since it's moving in both directions... But I never made one, so I don't know...
