I've only just started trying to do aerials, really, and I find myself getting vertigo from it haha. I'm also 40. It's so disorienting. None of the camera settings feel "right".
It takes some playing around with and is highly subjective. Best method I found was to just try camera configs used by pros or recommended by others and see what feels good. My current:
The rest aren't relevant for me because swivel speed is about looking with the right stick and transition speed is about switching to/from ball cam, and I leave ball cam on.
Of these, I believe the most important (by which I mean tangibly relevant to control quality/feel) are distance, stiffness, and, to some degree, height+angle. Shake and FOV are also important, but those are the only good values for those settings.
I used to play with max distance because it felt better for visibility, but I found some people saying 270/280 works much better for them for precise ball control and accurate strikes, and that does seem to be the case. Stiffness is the other setting that will make the most difference in feel: Lower values let the camera's distance from your car rubber-band further in relation to your speed. It might seem as if maxing this out would be ideal, because why wouldn't you want the camera to follow your movement as closely as possible, and why would you want the camera to lag behind you when you go faster and disorient you when you're trying to aerial? But I'm not so sure. I've tried stiffness at 1 (max) and I don't remember why, but apparently it didn't work for me, because I lowered it to 0.75, which I guess I found acceptable enough not to have changed it. I've just come across some people saying a stiffness of around 0.35 is counterintuitively great as it turns out that moving the car without instantly moving the camera helps a lot with car control for some reason, so I'm about to test run that value myself and see about it.
I also used to run with stiffness maxed out and I think it contributed to the motion sickness feeling. There's definitely a tradeoff in all of these values.
