I doubt you can mux ALAC into MP4.

If you must use MP4 then encode PCM inputs to AAC and stream
copy AAC inputs.

You can use ffprobe to determine the input audio format which is useful
if you want to script it:

$ ffprobe -loglevel error -select_streams a:0 -show_entries stream=codec_name -of csv=p=0 input.mov

Then use ffmpeg:

ffmpeg -i input -c copy -c:a aac output.mp4
or
ffmpeg -i input -c copy output.mp4
