I use 5-minute epoxy and flox for a lot of small non-structural parts. Lately I've been using it to bond in a bunch of little anchor doodads that I tie-wrap wiring bundles down to in my carbon fiber fuselages. In the past I've used those square nylon thingies, but the double-sided foam tape on them usually only lasts a few years, and I don't want to have to go in and replace them every few inspections.
As others note, a primary driver is how much you can mix and spread in the working time. It isn't much.
Right now I mostly use the Harbor Freight brand; it seems every bit as strong as the Gougeon Bros stuff I've used in the past, and is cheaper and locally available. I mix in a bit of flox for body, then tap in a few grains of carbon black to make it look more like structural adhesive.
