Uhm,.... If you are asking for the "best" in an unqualified statement the answer would be "resorcinol glue". That is what the plywood itself is glued up with. ... I will also say there really isn't much need to go to that extreme. It is my glue of choice and my 'go to' glue where I can. Followed by epoxy, and then by "Weldwood Plastic Resin Glue".
What has been suggested above is just fine.
