nandfs will work on NAND directly, but needs lots of work.

ufs works fine on eMMC since the eMMC parts do wear leveling
in the part. It isn’t designed specifically for that, but thousands
of systems are running ufs on SD cards just fine and eMMC is
the same thing (but with different low-level commands).
