I am setting up a home NAS for five users. Total amount of data stored

Clients are Macs and OpenBSD machines, so that SSHFS works fine from
both (no need for NFS or Samba).
I am much more familiar and comfortable with OpenBSD than with FreeBSD.
My dilema while stating the above is as follows:
Will the OpenBSD’s UFS stable and reliable enough for intended purpose?
Software-wise, OpenBSD's UFS is probably rock solid. The only possible
issues reported going years back is usage of softdep which is not
switched on by default so you don't need to worry anyway.
NAS will consist of just one encrypted drive, regularly backed to
hardware RAID encrypted two-disks drive via rsync.
I'm not sure this is the best strategy.
Should I byte the bullet and build the NAS on FreeBSD taking advantage
of ZFS, snapshots, replications, etc? Or is this an overkill?
ZFS is never overkill. Be you, I would consider to use ZFS for NAS with
2 drives in RAID1 -- so self healing is usable if some drive or cable is
not healthy enough. And then backup that to another ZFS box with again 2
drive in RAID1. If you would use kind of similar OSes there with the
same ZFS level support, then you would be even able to use zfs
send/receive functionality which will easy/speedup a lot your NAS
backups to the backup server/NAS.
