Do I understand it correctly that the default Gateway is for using Internet and talking to the "main"
Almost.
pfSense sends any traffic which has a destination address outside of the subnets defined on its own interfaces to the default gateway. So yes, packets to the internet are sent to the default gateway, however, packets to any other subnet which are not known by pfSense as well.

Another Gateway would be the 30.1 for the internal LAN connections in the Lab-Network?
You must not set a gateway on the LAN interface. You have to remove this again.
Additionally you have to set the "FritzBoxGateway" as default to get upstream traffic work.

And the static route i can just delete in the FB?
As stated above, you have to decide if you want to set up a routing a NAT network environment.
If you prefer routing you have to add NAT rules for incoming traffic for the 30.0 subnet on the FB directly by using the device IP addresses out of 30.0. In this environment you will still need that route on the FB and you should turn off NAT on the pfSense.
If you use NAT you don't need that route, you have to forward any traffic for the 30.0 subnet to pfSense and on pfSense you have to add further NAT rules to forward the traffic to the destination devices.
However, all that is not necessary to get internet access to work.
