Have you experimented with sleeping while fasted at all? I have heard a few people say they get their best sleep when sleeping on an empty stomach.
I also find white noise and a sleep mask have helped a fair bit. I’m a very light sleeper so little background noises wake me easily, so having white noise on helps there. And wearing a sleep mask notably improved my sleep as our bedroom can get quite bright (even with blackout curtains).
Anecdotally though, the most important factors for me are sun exposure (particularly morning and evening), weight lifting (or exercise in general), and cutting out caffeine.
