Can someone explain to me the difference between unRAID/TrueNAS/OpenMediaVault/Proxmox? And what to pick for a first-time NAS build?

Once OpenZFS allows for raidz expansion I'll definitely consider truenas -- assuming btrfs doesn't beat it to it by getting raid5/6 rock-solid.

  openmediavault is the next generation network attached storage (NAS) solution based on Debian Linux. Thanks to the modular design of the framework it can be enhanced via plugins. openmediavault is primarily designed to be used in home environments or small home offices.

  

I’d be wary of using TrueNAS as a first time build due to it’s poor expansion options - replace all disks in turn or add a new vdev. There’s no expanding vdevs at the current time like you can a mdadm RAID array. I’d be more inclined to run OMV (as the download is a Debian base) and potentially move to Scale later on once you know your true storage requirements and can afford to acquire all disks upfront. OMV is good to build bit by bit (I’m not convinced by Unraid). 2 x 10TB mirror -> 3 x 10TB RAID5 -> 4 x 10TB RAID5 or 6 etc.
