There should probably be a category for weather sweepers, though I don't know if it'd just be rain, sun, and sand mixed together or if they should be separate categories. Just naming it Weather (or Rain, Sun, and Sand) means you can also include setters like Uxie, Liepard, Regirock, and Hippopotas
Edit: Also, could Ludicolo go under boosting sweepers? Rain Dance is not exactly a set up move, but it essentially works the same way as one except the boost doesn't apply to all its moves
On that note, does Rock Polish and Agility fall into that category? Stuff like Rhydon and Articuno, and even some other more niche Pokemon like Lanturn, are all at least somewhat effective users
