I set up Proxmox on one of my Pi 4s (using an external SSD) and am quite happy with it. Runs four different LXC containers (one of which is a public-facing ActivityPub server for testing) and gives me zero headaches, so am currently looking for a beefier alternative that has a proper M.2 slot and at least 16GB of RAM...
I do wish that alternative boards had better OS support (especially the Rockchip ones, which tend to have weird kernel builds, etc),
