Ardour and jack will always communicate their audio via float (that is 32bit
real numbers). As only very few devices implement that, most devices are
talked to in integer-numbers. The newer ones are capable of doing 24bit
integers, some older ones are fixed to 16bit integers. So forcing jack to talk
to the audio-device in 16bit might give you lower quality during playback and
recording but it will not affect the internal quality of the sound processing
done inside jack and ardour and all the apps. And files exported from ardour
will also not be affected by that jack-setting.
