I usually run planar campaigns, and I typically start with the PCs around 5th level or higher. As a result of both the nature of planar games wildly varying in monsters by plane, and those added initial levels, none of the "fodder" monsters really tends to apply to my games. If anything I have more humans and planetouched as frequent baseline enemies
Though my current campaign didn't start out on the planes, it has ended up there in relatively short order, but it began on Golarion and I enjoyed the heck out of some of that setting's rather unique goblins while the PCs remained on the Material plane. Love those cute little murderous pyromaniacs.
