ReWired from Guavaman Enterprises (available here) is a great tool for mapping your controllers. The only thing it lacks is an easy way to map different icons to actions for different controllers. ReIconed2 takes care of that for you!
Starting with version 2.3 you can now select the update mode to fit your game: Active Controller (uses the last active input method), Prefer Controller (always uses attached controller if present), or Prefer Keyboard (always uses keyboard).
With over 300 images we've mapped every button for the XBOX controllers, PS controllers, Switch Controllers (including individual JoyCons™) and 129 keyboard/mouse inputs. Setup takes less than 5 minutes!
