Yeah btrfs maintainers still recommend against RAID5/6. You can sort of get around that by doing it via lvm and formatting that with btrfs, but I’d rather do it with native file system support. Fewer moving parts, as it were.
My own decision tree for these sorts of things is simple: are all the drives in the array the same? If so, zfs; if not, btrfs. Energy efficiency would come into play for spinning rust or arrays of sufficient size, but the “identical or not” question has served me well for years.
