I’d consider Arch too if you’re running ZFS on a client machine, there are like 5 kernel packages ready to go in the archzfs repo with ZFS baked in. I got tired of constantly rolling my own updated Debian packages for software a few years ago and made the jump to Arch and I’m really happy with it, the packaging and build system are a joy to work with compared to debs.
No disrespect intended to Debian here I just got tired of building so many packages to have updated software. EndeavourOS is a good place to start in the Arch ecosystem if you ever feel like checking it out. I run Proxmox on my server boxes as well.
