The word Simracer got "Sim" in it. So choose a sim and not an arcade racer. Games like Project Cars and Need for Speed might look cool in graphic terms. But that is not what a real sim game needs. I'd recommend to get started with games like Assetto Corsa, Assetto Corsa Competizione, rFactor2 and if you got too much money to spare, choose iRacing.
I'd rather also suggest, play the game on a PC and not on the console. Some games got released on both platforms but the physics are different.
Good look finding your sim!
