I lived through all 3, and I’ve always called them diskettes. My recollection is they were called that in the original Sony documentation, which appears to be elided from my brief searches this evening.
I’ll chalk it up to colloquial laundering, much like all 8P8C ports and cables now being called ‘Ethernet’.
Not a distinction that I ever heard, and I lived thought the 5.25" and 3.5" eras.

Lots of manufacturers called them lots of different things.
