When should I use font-lock-add-keywords() and when should I use
overlays to realize syntax highlighting?
Finally, in what cases should I prefer to use Toby Cubitt's auto-
overlays package?

I'd say, if what you're highlighting syntax, and the syntax is simple
enough, use font-lock.
If you're highlighting something temporarily or dynamically, use
overlays.
Otherwise, you can also directly set the text's properties as you're
parsing.
