Thanks for the inxi.   Old Mac, eh.
I searched a little, as I hear Macs can have quirks on linux installs   

LXQT.   Possibly not network-manager.    The terminal program is usually connman (or connmanctl) and I do prefer over network-manager.   The GUI is called CMST     
If you do have the connman base for LXQT and the CMST gui I would look there first via CMST/

The added steps of downloading drivers should not be necessary as Sparky automatically provides the non--free drivers and has your /etc/apt/sources.list populated with non-free and contrib.

https://wiki.debian.org/bcm43xx        ### Note as above you do not have to edit /etc/apt/sources.list - You are running Sparky     wiki page last updated 2020-09

http://michaelminn.com/linux/macbookpro8.2/
states that it likes    broadcom-sta-dkms    that info is from at least 1  version back from the present Debian stable.   You inxi states the driver loaded is   bcma-pci-bridge I do not know if that is the problem. 
#####    The above authors non-usage of systemd is probably his own opinion, and I strongly doubt that using systemd  is a problem.   

For a quick check that will not change your system you can try.   

"sudo apt install firmware-b43-installer"       ### the -s flag "simulates an install but does not perform.   

I am not a wifi guru (Oh I do miss DrXaos from the #! forum over a decade ago).    I see via the Debian wiki that there is a   https://wiki.debian.org/brcmfmac     but it is a different number than yours, the  43602.   

The often helpful but always use with caution ArchLinux  wiki talks about a possible need to black list.   

When dealing with drivers, the usage of dkms does make things much simpler  for new kernels.   

If someone else suggests the  usage of  broadcommsta-dkms   that might be something to try first.

" apt show broadcom-sta-dkms"    has more info. 

"sudo apt -s install broadcomm-sta-dkms"   will simulate, but of course will not show the actual build of the kernel module.   

 

Hopefully others with more experience will post.   I hope I was not as clear as mud.

Search forum for "More info easier via inxi"    If requested -  no inxi, no help for you by  me.
