Setup a raid5 with mdadm, format that with btrfs.
Using btrfs for raid is not recomended by btrfs itself.
But setting up a raid5 mdadm array is very simple and let you use btrfs.
I agree that zfs is too much.
Edit: with three drives, raid1 doesn't make sense. Raid10 i never seen it in over 20y being used by anybody.
