And therein lies your problem. "Everything auto connects" to system_1/2.
While this is a reasonable guess, it is just a guess and often wrong as
many audio IF have different ports for headphones, monitoring and main out
as well as digital (s/pdif). So auto connect works for a bunch of people
but is wrong for everyone else.

Auto connect is not a part of jackd or it's specification. It is done by
each application that chooses to do so. Some of them may choose to allow
you to auto connect to another set of ports besides system_1/2 (I don't
know of any off hand). However, the main problem with trying to have
applications auto connect to anything other than system_1/2 is that
anything else may not exist when jackd is started. So while things like
Ardour will reconnect to whatever it was connected to the last time it was
run, if what it was connected to last time is not yet started, that
connection will not happen. A workaround that is still maybe not finished
yet, is to run your jack application inside of Carla as a plugin. But
jackd itself does not come with such infrastructure.

Not that I have seen. The systray, indicator, notification area stuff
seems to have been a moving target and getting stuff to work right with it
has not been easy. Notification in xfce openes it's own floating window
which may not be where you want it anyway. I would think a real window
that you can put where you have space would be a better deal.
meterbridge -t dpm system:playback_1 system:playback_2
takes everything connected to playback_1/2 and reroutes them through the
meter. However, anything started after meterbridge still connects to
