I like Unraid... It has a UI for VMs and LXC containers like Proxmox, but it also has a pretty good Docker UI. I've got most things running on Docker on my home server, but I've also got one VM (Windows Server 2022 for Blue Iris) and two LXC containers. (LXC support is a plugin; it doesn't come out-of-the-box)
Docker with Proxmox is a bit weird, since it doesn't actually support Docker and you have to run Docker inside an LXC container or VM.
