Associate asked interesting question.

Is there any kind of listing of "modern" jet aces? And are any of those
in service today?

I'd guess best bet are the Israelis. Elsewhere some are from Vietnam
(US, Vietnam, Russian?) and what else?

There was air to air fighting at Eritrean-Etiopian war but I'd dare to
guess that total losses can be counted with one hand?

I'd limit the list to piloted aircraft also (no missiles, drones or
choppers).
