Gentoo:

/usr/local/lib/python3.9/site-packages/

"python3" means you can not have multiple Python versions installed
at the same time.  Bad.

I usually have 5 or 6 different Python's installed at the same time.
Makes it easy to test.  Not possible with lib/python3.

"dist-packages" is reserved for distribution use.  So avoiud them.
"site-packages" is for user installed packages.

You think that is confusing?  Check out virtual_env, and these
PEP 370 -- Per user site-packages directory

And there are proposals to make it much more "interesting".

Always better to go with what your distro wants.

No idea...
