I am a "black window man". I install fonts from other sources just by
unpacking or copuing them into the right directory known  to fontconfig and
fc-cach just happens automatically. I do not know exactly how it happens
but fc-cache is run automatically by root. I fact, I have quite a complex
system because I need (sometimes just for testin purposes) many versions of
TL thus I have almost everything since 2007. Then I have
/usr/local/textlive/current as a symlink to the currently used version and
my PATH contains /usr/local/texlive/current/bin/x86_64-linux. If I decide
to change it, I change the symlink, but for temporary modification I
manipulate PATH within the terminal. My /etc/fonts/conf.d contains the
following symlinks (I have a collection of commercial fonts and free fonts
downloaded from elsewhere):

07-zwfonts.conf -> /usr/local/zwfonts/conf/zwfonts-fontconfig.conf
08-texmflocal.conf ->
/usr/local/texlive/texmf-local/fonts/conf/texmf-local-fontconfig.conf
09-texlive.conf ->
/usr/local/texlive/current/texmf-var/fonts/conf/texlive-fontconfig.conf

"current" in the middle of the names works fine as the symlink. And when
(after I complete important work) remove current (it is now symlinked to
2023) and issue

ln -s 2024 current

then as always before fc-cache will update the font cache automatically. In
the past fc-cache was needed but now fontconfig takes care. You will need
fc-cache if the font system gets corrupted for some reason.

I still do not know how to work with fonts on Mac, it sometimes works with
symlinks, sometimes not. The old models of Raspberry have low power
consumption so that they can be powered frm Macbook's USB and connected via
an ethernet cable (Macbook detects the polarity so you do not care which
type to use). My Raspberries are configured to get the IP address from DHCP
thus I configured the DHCP server on Mac but only on ethernet, not on WiFi.
Thus I know how to find the IP address of the Raspberry and can ssh to it.
I have a SSH server running on Mac thus when I am on the Raspberry, I can
mount a directory from the Mac via sshfs. I thus run TeX on the Raspberry
using the mounted directory and use a text editor and PDF viewver on the
Mac. And all my fonts are in texmf-local and due to limited space, I have
only one version of TL on the Raspberry. My texmf-local is on my subversion
server. Thus I install the fonts into texmf-local on one of my Linux
computers, do "svn ci" and after "svn up" on the Raspberry fc-cache just
happens and the fonts are known to Xe(La)TeX. I do not know how it works
internaly but it works.
