You’ll need to experiment and see what works for your body. We’re all different and don’t respond the same ways

For me: OMAD is \~4:30-5:00pm. I digest through the evening when nothing is needed from me. Off to bed \~8:30-9:30pm and am fine. If I eat later, digesting keeps me up. If I eat earlier, personal health issues with digestion ruin the rest of my day. You need to play around and see where to place your meal in a way that works best for you
This is very common. Two things:
Magnesium does wonders here. I take one pill in the morning, one an hour before bed. It has helped me a lot!
I also noticed I’m more sensible to things that would already affect my sleep in normal times. I try not to take caffeine at least 8 hours before bed, cut out blue screens and other stimulants at least one hour before bed. Also, if you can, ear plugs and a sleep mask help a lot.
There’s usually some sleep disturbance. However magnesium can help, also I’ve found that taking some psyllium husk a little bit before bed makes it easier to sleep. Melatonin can also help, (less can be more here, I’ll often split a 3mg pill in half).
