My current inventory of glue is the following. Titebond wood glue, Greatplanes 15 min epoxy, Greatplanes thin and med CA, and canopy glue. I use the wood glue as much as possible, it is non toxic and cheap. Epoxy for critical joints and sealing firewalls etc. I do not like using CA but it speeds things up if your in a hurry and is good for quick repairs. everybody builds differently but I think most modelers will agree you need epoxy for critical plywood joints and the rest is personal preference. Use Canopy glue for as its name implies. CA will damage clear plastic. Never tried Gorilla Glue but sounds like a winner for certain applications.
