TV / Internet combo for dummies?

I have not had a TV for over 3 years. Before, there was only the usual cable TV. But now I wanted to inform myself about it. Possibly. Does any of you have any advice?

I use my laptop so far for series and guided yoga lessons, etc. On Youtube. Would like to run but over a TV. But now there are so many unnecessary combinations of providers, where I just can't see through. Netflix, Amazon, Telekom, Smart TV, etc. I do not want to spend money unnecessarily on something that I do not actually use.

All I want is a TV package, where I can watch series / movies for free, the usual program of RTL-Pr7 and transfer from Youtube to TV.

Do you understand what i mean? Just an Internet / TV combo or something

TV Internet station wagon you get from your provider or cable TV provider. Netflix and Amazon, etc., you can then book.
