The main reason I never tried OpenStack was that the official requirements were more than I had in my home VM host, and I couldn't figure out if the hardware requirements were real or suggested.
Proxmox has very little overhead. I've since moved to Incus. There are some really decent options out there, although Incus still has some gaps in the functionality Proxmox fills out of the box.
