Just about all glues are stonger than plywood or balsa. Therefore as long as you got a good bond then the glue joint will not fail but the wood will. The decistion on which glue to use is mostly based on it charateristics of use.

What I use:
-thin, medium, and thick CA
-pro-bond instead of epoxy when I don't mind waiting - also it can be sanded much easier than epoxy
-12 & 30 minute epoxy
