I note I can set a preferred language in the TVheadend configs but I ask because I have a TV that whilst I can set a preferred language, it ignores it and I always have to select the language channel.
This sounds like a question for Kodi.

From my experience, Kodi puts a greater demand on a system than tvheadend.

Provided that the network location is mounted into your file system and that the user running Tvheadend has access, then yes.
Have a look at LibreELEC. It is a minimal Linux distribution with Kodi and Tvheadend built-in: https://libreelec.tv/
There is a version for the Raspberry Pi. Perhaps there is also some documentation there regarding models and system load.
