How should I fill the 4 paddles for Fortnite?

I recently started doing Fortnite again. Now I ask myself which action I should put on which key. Got the Nacon revolution unlimited per controller. So the back is more like buttons and not paddles. But that's not so relevant to my question. Maybe someone can help me.

I would edit, build menu, maybe take pick and emote or something.

Jumping is also very important so that you don't have to get off the stick

Editing, tree menu, pickaxe and jumping are the best

Right
