The only thing that makes CA better than wood glue is it's "instant set" properties. You can build quicker with it, but in actuality CA is pretty brittle when it cures, so in that respect wood glue is better.

Epoxy, especially the stuff that takes longer to set like 30 minute, is quite a bit stronger than wood glue I believe. You only need it on things like joining the wing halves, and installing landing gear blocks and firewall; the stuff where you want added stregth.
