I have been using Autosleep now with an apple watch 6 - for 3 years daily.

The learnings and the gamification are huge for me. I got my deep sleep up from 1.5h to consistently over 2h.

Learnings:

- early to bed makes more deep sleep. Huge difference from 10pm or 12am

- magnesium doesn’t help at all

- sauna before does help, but hard to do daily

- deep sleep less than 1.5h makes for an awful day with angry mood

- cold room: biggest lever. Haven’t pulled the trigger on an 8sleep yet. But that wouldn’t be my next thing if sleep wouldn’t be so great.

- also, as weird as it sounds: having something exciting to work on improves sleep by a lot.

YMMV

From Apple Watch, I learned I get 11 minutes of deep sleep last night, and generally average well under half an hour (for a full 8 hour typical). I can fall asleep easily, but apparently not very well. Yours sounds great.
