I guess I do also sometimes use it for ephemeral things without having to worry about cleaning up after too. E.g. I can dork around with some project I saw on GitHub for an afternoon then hit "revert to snapshot" without having to worry about what that means for the permanent stuff running at the same time.
I found Turnkey Linux pretty nice. They provide ready to use Linux images for different services. Proxmox integrates with them, so for example to install Nextcloud, all I needed to do is to click around a bunch on the Proxmox interface, and I'm good to go. They have around 80-90 images to choose from.
I like having a local server I can carry with me and control using just Cursor to manage it.
So basically the freedom that comes with a homelab without using proxmox UI and ssh.
