If you’re planning to go BSD, or buy all the drives you’re ever gonna have in the cluster up-front, then ZFS is great. Otherwise, be mindful of the hidden cost of ZFS. Personally, for my home server, because I’m gradually adding more drives still, I’m using mdraid on RAID6 with 8 x 8TB WD Reds/HGST Ultrastars, and I’m loving the room for activities.
Having said that, regardless of the solution you go with, since you’ve got only 4 drives, higher RAID level (and equivalent of thereof such as RAIDZ2) might be out of reach as you’d be “wasting” a lot of space for the extra piece of mind. If I were in your situation, I’d probably use RAID5 (despite RAID 5 is dead in 2009, or have they continued chugging on after 2013) for less important data (so sustain 1 drive failure) or RAID 10 if I need more performance (and depending on luck of draw, potentially sustain 2 drive failures depending on which drive fails).

Thanks. I believe TrueNAS does ZFS as well… maybe by default. If I want to keep it simple this will probably be the route I go.
