There are a few different meanings of "zu" in these sentences, like:

- relating to
- for the purpose of
- supplementing

Let's take a look at some of your example sentences:

- Fragen zur Person (questions about the person, lit.: "questions relating to the person")
- Hören Sie zur Kontrolle (listen so that you can check, lit.: "listen for the purpose of checking")
- Zusatzmaterialien zum Buch (additional material supplementing the book)

If you think of "zu" like this, I think you will be able to understand it better.



"Übersicht über" and "Übersicht zu" can be used interchangeably. There's no real difference between these two.

I hope I could help you!
