I have had a chance to test the issue on friends' laptops so here are two more data points. They have only version 4.3.1 I believe, not the latest HEAD. Their built-in mic sample rate is 48000Hz (I suppose more recent laptops updated it?).
1) MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports) Processor 2,3 GHz Intel Core i5 No issues, captured audio sounds fine. 2) MacBook Pro (13-inch, 2019, Four Thunderbolt 3 Ports) Processor 2,4 GHz Quad-Core Intel Core i5 Missing audio samples as in my case (even more so), and the captured audio sounds even worse... So unfortunately it looks like a problem with ffmpeg's avfoundation implementation at this point...
