Its also quite difficult to find 2280 M.2 SATA SSD. Had an old laptop that only takes 2280 M.2 SATA SSD.

Its always one of the 2. M.2 but PCIe/NVMe, or SATA but not M.2.

Fwiw, SATA and NVMe are mutually incompatible concepts for a single device; SATA drives use AHCI to wrap ATA commands in a SCSI-shaped queuing mechanism called command lists over the SATA bus, while NVMe (M.2/U.2/add-in) drives talk NVMe protocol (multiple queues) over PCIe.
