Nintendo Switch console: transferring data?

I've already found a post on how this works: https://www.nintendo.de/...49113.html

I just have questions left open to me. Does this also transfer the playing time that you have already invested or just the game data? And what about screenshots and videos on my old switch, can you transfer them?

I've had a Nintendo Switch for a few years and now I want to buy the Animal crossing Edition.

Maybe someone will read my question who has already done this and can explain to me what exactly is transferred or what can be transferred

Yes, I used it to transfer my scores. I think screenshots work too. Game times and various other things are saved online on the Nintendo user.

Thank you very much.
