What is a recommended XFS sector size for hybrid (512e) advanced format hard drives?

A common theme emerges, so far 6 for 6 drives behaving this way are in
USB enclosures. At least one vendor ships an external drive (drive
inside an enclosure) that causes parted to report 4096B/4096B
logical/physical sectors. The drive inside is actually 512e so it's
512B/4096B, and the result of this is that partitioning/formatting it
inside the enclosure means it's completely unreadable outside the
enclosure and vice versa. So cute and adorable.
