> I imagine some kind of numbered, curated list of radio achievements
Yes, this is widespread. The ARRL in the US tracks such achievements. A simple example that comes to mind is Worked All States[1]. But that's just one: there are contests, events, records, etc. If you want to put your callsign on a list somewhere there are lots of opportunities.
Just having a callsign in the first place is the start of it. Those are usually assigned by whatever national government you live under. And they typically have grades: Technician, General and Extra in the US, for example.
