I think I should find a USB-LAN-Adapter - do they work with TrueOS? Are there any recommendations?


TrueOS is on top of FreeBSD 12.0-CURRENT. so any of them that works with FreeBSD, it should just work.

A place to start ->

I’ve used --> Alfa AWUS036H 1000mW 1W 802.11b/g USB Wireless WiFi network Adapter with 5dBi Antenna and Suction cup Window Mount dock - for Wardriving & Range Extension


Ah, OK, thank you and sorry for I was not thinking of WiFi, WLAN, but on a proper copper connection. Even more accurate, preferably USB-C to Ethernet cable.
