Would only be worth it if you created a system for easily deploying applications on an already set up subnet with routing preconfigured.

Like set up a single server kubernetes distribution like microk8s or minikube on the server with metalLB and ingress already preconfigured on the server and router. You could also give instructions on how to install a GUI like Lens and how to use it to deploy a few things. Probably using workstation applications would be better than a web UI like Portainer to keep the server lighter, but either might work.
