According to CanIUse.com [prefers-color-scheme] support is at around 78%, leaving out Internet Explorer and Edge (not Edge Chromium).
Correct me if I'm wrong, but I don't believe browser support is enough for this feature to work properly - you also need a way to set your theme preferences in your OS. I think this is only available on Android Q (Android 10), and I am yet to find a way to set this as a preference in KDE. (No clue about OSX, Windows, and iOS, as I don't use them and had no need to research it so far).
I think it's a bit too early to adopt this, as most users will have older phones.
Using both is the preferred option. Support in OS/Browsers for prefers-color-scheme will only increase. Which means if you implement now, you will support more users in the future, rather than doing it later.
Secondly, in initial hit of your site, you can set their preferred theme according to their preferred color schema (dark mode on first hit). If you only rely on a toggle, you force users to use the light mode regardless of their preferred setting.
Admittedly, I should have worded this better, as that is what I do. Check for a LocalStorage preference that I set when the user toggles dark mode, and check the schema if the key isn't set.

You can always fallback to light theme in case this feature is not supported.
Of course. Better yet, do use a toggle, and don't rely on something unreliable :)

Correct, combining both is the best idea.
