Thin CA on balsa to balsa, 30 minute epoxy on hardwood to hardwood or high stress areas like the fire wall. I usually keep a bottle of titebond on hand as well as Sigment. Sigment is pretty good for things like balsa doublers where titebond tends to warp the large areas. I also use Gorilla glue for things like wing tubes and sometimes hinges.
A lot of time I will have 6 different types of adhesives on my bench but I use so much CA that I buy it in 8 ounce bottles. I like the speed in setting up. When I build I don't like waiting for glue to set up but these days I will also go out to the shop, epoxy in a part and not go back out to the shop again until the next day. I have slowed down a lot the last couple years. Not slow enough to just use titebond though.
