M.2 SATA drives are still a thing, same port, but different slower protocol as NVMe. They are less common, but still around and available in TB size. Don’t think there is any reason to get this outside of compatibility with old hardware.
There is also mSATA, which is a different port from M.2, but has a very similar look and size. Also slower than NVMe and no reason to get them unless you have hardware that uses them (e.g. some old Beelink miniPC have them).
