a paper I wrote some time back for this forum, broadened a little and posted to the SO website.
It doesn't say much on epoxies, PVAs (elmers style wood glues), or polyurethanes (gorilla glue) as they don't have much practical use in WS. All fine glues in the appropriate circumstances, but WS doesn't have much in the way of appropriate circumstances for these glues.
Key points. The quality of the joints is critical to using minimum amounts of glue with strength. Once you have that, balsa cement or CA is a matter of preference and which YOU can maintain minimum weight gain with.
