Tips for an old man.

I bought a PS5 for my son, and I've started playing GT7 quite frequently. I have no experience; it's my first time playing.

I'm doing the café missions and getting the licenses. I think it's the best way to learn, but I have some questions:

(I) I've been playing with all the assists, and I intend to gradually remove them as I feel I'm improving. Is this a good idea, or could it hinder the learning curve?

(ii) I've been playing with the original controller. So far it's been very fun and challenging. But I wonder if this significantly hinders the experience, especially as I eventually improve?

I would appreciate any tips for a 47-year-old man to learn to play and have fun with his new hobby!
