Posting the second part, corresponding to what I did with ChatGpt aid.
chatgpt concoction; VLC also refuses to play the audio but generates the two subtittles:
ffmpeg -i movie.mkv -vf "scale=-1:802,format=yuv420p" -map 0 -c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main -c:a aac -b:a 192k -c:s copy -disposition:a:0 default 8c_movie.mkv
CLI outputs:
cer@Telcontar:/mnt/nfs/Isengard/xfsRaid/Videos/tmp> ffmpeg -t 10:0 -i movie.mkv -vf "scale=-1:802,format=yuv420p" \
