Thinking about switching away from TrueNAS scale to OMV (lemm.ee)

As the title says i am currently considering switching away from TrueNAS Scale.

My system has a Celeron N3160, 16gb ram, 2x18tb HDD as a zfs mirror and ssd storage for os

My usecase is mostly just as a local storage and media server with *arr stack and jellyfin.

Some of the reasons why i want to switch:

Truenas claims a full drive for the OS, no way to partition off something
no automatic updates (i get why it might make sense for stability, but as a basic user i probably value the convenience higher)
there've been issues with truecharts breaking the ability to update and the solution seemed to be to just reinstall the applications
applications sometimes don't show up on start and i have to restart

Overall i think TrueNAS Scale might be excellent for some, but i am just not quite the target audience. So i just want something simple that works.

Now that Unraid supports ZFS that would be a consideration, but i don't really feel like paying (however i am not completely opposed, if its the best option).

My first idea was Proxmox, but thinking about it a bit more i probably don't need the flexibility and it just adds more levers that need adjusting.

So the current frontrunner would be OpenMediaVault for a simple NAS setup that doesn't need as much flexibility and is low maintainance. I assume the setup would be pretty straight forward and i can just import my truenas zfs pool and install whatever docker applications i want.

My questions would be:

Is OpenMediaVault a good choice for me? Or is there anything better?
Any up/downsides compared to e.g. something like a simple ubuntu server?
Is there anything major that i would miss out on by not going with proxmox?

Somewhat late reply, since i didn't have the time to start my conversion to OMV sooner. Definitely looks nice and installation was easy.

You are spot on that my first issue has partially to do with permissions. Following a guide at the time i structured my media library to some level with data sets in my zfs pool on truenas scale. But those apparently are more like filesystems rather than just directories. Which makes the whole giving permissions for my dockeruser a bit difficult (and also otherwise seems a bit less then ideal for OMV).

So since i wanted to structure it slightly different i made a new shared folder on my zfs pool and directories for my media in there and moved a few test files. Downside now is that this solution would mean that i have to move a ton of files, which would mean a ton of writes to my drives.

Apparently they changed that in one of the recent updates, but so far i really like the setup with docker compose. So much easier than the whole deal with applications in truenas scale. Copy+Paste stuff into a file, change some variables and a full stack of media applications is up and running so fast.
