There will almost certainly be a resampling stage if you pipe audio
between JACK and Pulseaudio.

It's common for applications to ignore monitor sources when presenting a
list of sources to pick from, however if your application allows for a
device name to be specified directly, you can select the monitor source
Alternatively, you can redirect an existing source output to a different
source programmatically by using "pactl move-source-output", or by using
a grapical utility like pavucontrol.
