Proxmox vs. Debian: Running media server on older hardware (lemmy.world)

I'm still running a 6th-generation Intel CPU (i5-6600k) on my media server, with 64GB of RAM and a Quadro P1000 for the rare 1080p transcoding needs. Windows 10 is still my OS from when it was a gaming PC and I want to switch to Linux. I'm a casual user on my personal machine, as well as with OpenWRT on my network hardware.

Here are the few features I need:

MergerFS with a RAID option for drive redundancy. I use multiple 12TB drives right now and have my media types separated between each. I'd like to have one pool that I can be flexible with space between each share.
Docker for *arr/media downloaders/RSS feed reader/various FOSS tools and gizmos.
I'd like to start working with Home Assistant. Installing with WSL hasn't worked for me, so switching to Linux seems like the best option for this.

Guides like Perfect Media Server say that Proxmox is better than a traditional distro like Debian/Ubuntu, but I'm concerned about performance on my 6600k. Will LXCs and/or a VM for Docker push my CPU to its limits? Or should I do standard Debian or even OpenMediaVault?

I'm comfortable learning Proxmox and its intricacies, especially if I can move my Windows 10 install into a VM as a failsafe while building a storage pool with new drives.

MergerFS and SnapRAID could be good for you. It's not immediate parity like with ZFS RAID (You run a regular cronjob to calculate RAID parity) but it supports mismatched drive sizes, expansion of the pool at any time, and some other features that should be good for a media server where live parity isn't critical.

Proxmox and TrueNAS are nice because they help manage ZFS and other remote management within a nice UI but really you can just use Debian with SSH and do the same stuff. DietPi has a few nice utilities on top of Debian (DDNS manager and CLI fstab utilities, for example)but not super necessary.

Personally I use TrueNAS but I also used DietPi/Debian for years and both have benefits and it really matters what your workflow is. OMV supports everything you want too (incouding SnapRAID) but takes extra setup which put me off.

Docker or LXC containers won't hurt your performance btw. There's supposedly some tiny overhead but both are designed to use the basic Linux system as much as possible: they're way faster than on WSL. For hardware acceleration it'll be deferred to the GPU for most things and there's lots of documentation to set it up. The best thing about docker is that every application is kept separate to eachother - updates can be done incrementally and rollbacks are possible too!
