Truenas is great for creating the zfs pool but I hated that I couldn't also use the machine as a computer without making a vm, so I ended up exporting my zfs pool and then importing it on a Linux system with cockpit installed to keep a Web interface, definitely recommend looking into it
Arch on my main pc, and Ubuntu on my server, only reason it's Ubuntu is I needed 6.2 kernel for my Intel arc encoding card and debian based for the arrs
I did the same as you, but wanted native performance on my Linux machine, so what was awesome was I was able to export my zfs pool from truenas and spool up a Linux distro and import it. There's a project called cockpit and it has a zfs plugin which makes it easy to manage like truenas, but you can also use it as a whole ass pc at the same time
