I have built quite a few planes over the years now, and the best to use for general framework is thin CA. Medium and Thick CA is usually used in areas where you need a little extra strength, such as known stress areas, but not critical ones, such as horizontal and vertical stab attachment to the fuse frame. Some prefer epoxy for this, but usually thick CA is fine. I personally use Epoxy to provide time to set it in place properly. Thick CA is good for plywood and hardwood parts as well. Do not use thin CA on Plywood or hardwoods, it does not penetrate well, thus the joint tends to be weak.

For areas like joining wings, and firewall adhesion, use 30min epoxy only. These are critical, and there is no substitute for good 30 min epoxy. 30 min epoxy is also good for thinly coating the front of the firewall, and the interior of the fuse around the fuel tank to fuel proof the wood incase of minor leaks.

A very good alternative to CA is one that I like alot as well, and that is regulat Titebond Wood glue. It is water soluable, and easily cleans up. Also, it has no stinky fumes. The drawback, is that it takes time to dry. But, if used correctly, it really is nice stuff.
