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.

If rebuild time is truly your main concern, you could configure the 4 drives as raid 1+0. On truenas I think it would be called a pool of 2 mirror vdevs. It would give you much faster rebuild time and still have 1-2 drive failure tolerance.
