This answer may not be useful for you but the only recommended way of
installing Python modules system-wide is by making a proper Debian package
for them using proper Debian Python packaging helpers, and the only other
recommended way of installing Python modules is venvs.
If I needed to install this I would use either of these two, depending on
whether I actually need to have it system-wide and whether I want an
official package uploaded to Debian.
Alternatively, as you mentioned /opt, if the software supports installing
*everything* in /opt (maybe it adds that to sys.path when it runs), then
doing that is also fine (as it doesn't touch things outside /opt and
cannot break those).
