Using some tag with “audio” in it could be confusing because these plugs are also used for other stuff, such as power supplies and (old) telephones, and in some posts you can’t even see what they’re being used for. “trs connector” is only for the single-ring type but these plugs can have zero to three rings (ts to trrrs). jack plug is the most generic and application-neutral name for this kind of plug.
The original telephony purpose for these was still audio, and I'd argue that usage for power (which you do see) is pretty nonstandard, usually you see barrel connectors for low-voltage power purposes. That said, I don't have a real strong preference here, just saying I've never heard anyone say "jack plug". It's usually some sort of "jack" or some sort of "plug", but never both together (in my experience anyway).
TRS or TRRS is technically accurate, but also very technical. You don't see that description much outside of electronics suppliers.
