To give another N=1, I don’t feel good on a 16:8 split. At least not when the eating window starts at noon. Long term (18 months) this zapped my energy and I lost a lot of muscle. Yes, weight loss was phenomenal, but I gained all of that back in the phase of exhaustion that followed.
What has worked better for me was longer fasts, eg 48h, max once per week. And lately I‘ve been experimenting with skipping late dinner (no food after 6PM) which is kinda hard but seems to work for improved sleep and digestive health. I usually have visible bags under my eyes, those tend to be greatly reduced when I eat an early or no dinner.

Muscle loss is an adaptation to loss of load on the muscle. Internet trope of "you lose muscle when you lose fat" is just that - a trope. If you were 100lb heavier, your muscles were loaded with extra 100lb. Should you lose the 100lbs, if you do not engage in the appropriate resistance exercises to provide equivalent of additional 100lb load, your muscle mass will decrease
