Hey Christian, to answer your questions, there is no Lab licenses for physical hardware. There are also no "Lab" VE licenses that are over 10Mbps either. That said, nothing should prevent you from using a 10Mbps Lab VE on a 1Gbps network.
Next, have a look at the Community Labs over at https://clouddocs.f5.com/training/community/. These labs are delivered initially at the F5 Agility Conference but made freely available afterwards for anyone to replicate and learn from in their own environments.
