Best guide I've found when setting up a homelab with TrueNAS Scale
From Wendell, Level1Techs.
Why I personally think it's the best:
It gives you more control and make total use of your storage. In this guide, he doesn't even use the 'Apps' feature on TrueNAS Scale, instead it's just way better to spin up a VM that you have control to. People may ask, but why not Proxmox? yeah you could - but what if you already have a TrueNAS Scale system? Anyway these discussions would lead to a bunch of opinions & fanaticism. This is also noob-friendly.
Just check it out. At the very least you'll know one way of doing it.
