Review on 🎮 Hori PlayStation 4 TAC Pro Type M2 (Doom Edition) KeyPad and Mouse Controller - Officially Licensed by Sony & Bethesda - Perfect for FPS Games - PlayStation 4 by Julie Weigel

I can't use my controller to play FPS, this just saved me. The included mouse is a bit cheap, I connected my Logitech G wireless mouse and it works fine; Just remember to turn on the mouse before activating the keyboard, otherwise you'll have to unplug and plug the USB receiver back in, but your mouse will plug in immediately.
