Regarding magnesium, the specific supplement you happened to link to was magnesium oxide. There’s some evidence that magnesium oxide is less bioavailable than other forms of magnesium (1,2,3) It’s true that magnesium oxide is cheaper, but magnesium citrate is still exceptionally cheap (a few pence per dose). So, even if you are uncertain about the benefits of other forms over oxide, I think it’s still probably reasonable to err in favour of these other forms.
I think it’s also worth thinking about glycine. There are a few papers suggesting that glycine improves sleep quality (4, 5, 6, 7). You could also take magnesium bisglycinate, which contains both magnesium and glycine, but aside from convenience of only having to take one thing, I don’t see any advantage to doing that rather than just dosing them separately.

Agree that the quality of magnesium matters!
