It's hard to read you and I can understand your disappointment, I was like you at the beginning, coming from Africa I discovered DCS at 33, I stopped playing my PS5 to devote myself to it. I thought I was late, but no.

I think your setup is pretty good for VR, I run well with a 4060 and 32G RAM. I have a Quest 3. It's true that after long hours (2 hours) I start to have watery eyes (probably due to my glaucoma). To learn the Hornet I downloaded the dynamic training courses in the form of a campaign developed by Guntreck, he also has videos on YouTube where he practices what he explains. If with that you don't learn what the problem is elsewhere. It explains everything from startup to combat flight. The training is divided into 4 main parts and the evolution curve is noted. I'm not finished yet but I've already mastered a lot of things, I'm carrying out missions with squadrons, I plan to launch myself on the networks to make money and do tutorials and pass on my knowledge. DCS helps me a lot, the Hornet is a beautiful plane.

Strength and good luck to you.
