There was a video I saw once several years ago that claimed to sync up ATC audio and flight radar of commercial and military traffic, but I haven't been able to find it since despite a couple cursory searches here and there.

IIRC, it was a custom animation/overlay like they use in documentaries and newscasts, not a screenshot of FlightAware or anything.

Any chance anyone knows what I'm talking about and has a link?

I'd be interested in seeing that as well. The only thing I can think of that is similar is the interactive Apollo 11 in Real Time: https://apolloinrealtime.org/11/
