I have a rather jaundiced view. Every time the word 'legacy' rings, an angel in heaven is entitled to use the word 'weenie-ware' one more time.
Since the term 'data set' (is it one or two words?) is pretty much confined to mainframe, 'file' is useful for communicating to the unwashed masses. To avoid ambiguity, I try to use 'MVS file' or 'VM file' to distinguish it from Unix or Linux, both of which (can) live on mainframe. The problem with 'z/OS' is that it's a marketing/packaging term that is subject to meta-technical whims in the IBM boardroom. BTW we once had a pitch on Linux on z that referred to traditional Unix applications as 'legacy'. Sweet. . .

"Dataset" is a z/OS legacy term that applies to the entries in a VTOC and z/OS catalog. Note that I try (but fail on occasion) to _NOT_ call datasets "files". Because UNIX data containers are called "files". So, for me, I use the terms "legacy dataset" or "UNIX file" respectively for these data containers. And, just as a by-the-by, I consider a UNIX filesystem container to be a "legacy dataset" because it is basically an VSAM LDS and so is in the z/OS catalog and has an entry in the VTOC(s). Also, you can manage the filesystem container using things such as HSM, ADRDSSU/FDR, and so on. Said programs not being usable with individual UNIX files. So, how can I confuse more? -- "Irrigation of the land with seawater desalinated by fusion power is ancient.
