Can't add you on discord for some reason :(
Thanks for your elaboration helps a lot. But I disagree with you when it comes to the control during jumping. I had a different version before where the player had full control and this just felt wrong and terrible to control.
For the camera I can not take any credit. I started with the Unity 3D Starter Assets which include a Character Controller which served as my base for the movement. This class includes all Camera Controls.
