Of these 2 choices, the X570 TUF for sure. You might be better off saving some money and going with a decent B450 motherboard though, if you're not going to use a PCIe 4.0 SSD.

The Rocket 4 is a PCIe 4.0 NVMe SSD. The Crucial P1 is only PCIe 3.0. So, the Rocket 4 is over twice as fast as the P1, but the P1 is already very fast compared to a SATA SSD anyway. So, the Rocket 4 is better but it's also probably a lot more expensive, in which case a PCIe 3.0 SSD would do absolutely fine.
I personally have a PCIe 3.0 Sabrent Rocket.

I imagine these are both in 2 completely different price points again? Both perfectly good quality units though, so either would be fine. There are also probably some other good options. Would need to know your budget and currency to be able to recommend parts though.
So, what is your budget and local currency?
1600 Euros? Netzteil is German right, so I take it you're purchasing in Germany?
What exactly will you be using this system for?
Overall you seem to be going in the right direction IMO, but I'd make a few changes probably.
I'll need to know the answers to the above questions to be able to recommend specific parts though.
