Your previous output indicated that jackd (traditional JACK server) is 
installed and pipewire is the audio server active.

If you wish to use jackd then start jackd with the options you want,  and if 
pipewire is using the device you configured jackd will request exclusive 
access, and the pipewire server will release exclusive access of the device 
while jackd is running.

If you with to use pipewire as the JACK server then install the pipewire-jack 
modules and the pipewire server will provide JACK as well as Pulse API for 
applications to use, along with ALSA plugin emulation for applications which 
can only use alsalib (different than e.g. jackd or Ardour which only use ALSA 
hardware devices).

You still have not yet installed pipewire-jack.  The output quoted above shows 
that your pipewire server has pipewire-pulse and pipewire-alsa API active.

The pw-jack plugin is for pipewire server to act as a JACK client in the case 
that jackd server is running.

That is different than the application pw-jack, which is used to set the 
library path to libjack.so in cases where ldconfig is not set properly to point 
to the libjack provided by pipewire-jack (which you do not have yet because 
you have not yet installed pipewire-jack).
