@viragomann Thanks a lot!
I had to reconfigure the LAN and WAN assignements upon reboot, which was not that hard. Then the vlans had to be redirected to the new LAN. And it is working.
I do have some questions on the outcome.
My LAN interface still does not have an option for 10Gbase-T. It only has autoselect.

Speeds are definetely better, but far away from 10Gbit/s.
Is this normal? Is there any other configuration I have to do to get the right intel driver for the interface in pfsense?
I was looking at CPU usage and it goes to about 9%. Once it hit 30% when running iperf3 -P 10. Which resulted in lower speeds in sum :/
I do have a high MTU set on the network adapter of the windows PC I am running as the iperf3 client. And I haven't changed anything regarding that on pfsense. I imagine that could be the reason for not reaching higher speeds. Different MTU settings?!
