FS2020 has some simple tutorial missions for taking off, landing, etc. Other than that there are loads of great YouTube channels such as Squirrel that walk you through things https://www.youtube.com/playlist?list=PLbphwhPw2JuvwwsD-H3xo...

As for hardware, I'd recommend at minimum a joystick of some kind if you don't have one.

And finally I'd give you a shameless plug for my app SmoothTrack which lets you fluidly control the game camera with small head movements - https://smoothtrack.app ;-)
