A light file/media server definitely doesn't need NVMe.

I agree, but I was stressing it's there if I choose to recycle an old disk.

If you're to the point of having spare NVMe drives, I suppose, but USB adapters are $20-25 and they'll perform fine for that use.

Edge servers need NVMe.

Not light ones. They'll do fine despite the extra microseconds.
