Thx for your fast answer Eugen!

Let me clarify:

The video should be 16:9 but the padding inside the file should be dynamic  – depending on the actual ratio of the recording.

I don't think this is supported in mp4.
(I am not claiming that it would work at all with FFmpeg, but if you want to put the result in mp4, I suspect it is

Or do I misunderstand and all you want it either 4/3 in the whole file or 16/9 in the whole file (that should be the current behaviour).
