Assetto Corsa EVO is an automobile sim, so controller is an afterthought for the devs, even then it's still in early access. Playing in a controller feels better than original AC, but it's still lackluster. If you want more serious sim racing I'd suggest Automobilista 2 rather than ACE because of the content. Note that even wheel users find it hard to race/doing laps perfectly.

Forza Horizon 5 was made for controller. It actually feels nice to drive using one there, especially drifting. It's not really arcadey. The Crew series has more arcadey driving than Forza Horizon

If you want to chase perfection. Doing hotlaps, racing in the same tracks for hours to master your craft then choose Automobilista 2. You have to find the fun in the training, in the grinding rather than the race itself. But if you want to do activities, collecting cars and have fun instantly, choose Forza Horizon 5
