Raidz2 or btrfs for important document storage? (piefed.blahaj.zone)

I currently have a secondary pool (with raidz2) that I was originally going to use for my important documents, such as storage for Paperless-ngx, as raidz offers corruption detection and repair. The pool is encrypted.

However, I'm concerned about rebuild times (it's a pool of 4 22TB drives). Is btrfs a better choice for this use case, or should I just go with raidz like I originally planned?

Edit: I should have mentioned that I already have 4-3-2 backups configured - I'm primarily interested in the "self-healing" aspect of ZFS so that I don't have to recover from backups unless necessary, and to resolve corruption on the fly without me having to notice that a file is corrupt.

I have been enjoying using ZFS, although it's a not a killer filesystem for every scenario, I think it would be the best solution for you. also, you can try the "free consulting" on the 2.5 Admins podcast (show@2.5admins.com). Jim and Allen are ZFS lovely weirdos, but they can explain better why would be ZFS a better solution for your case. Give it a try. I have done it before and really helped me.
