I'm quite fine using the Git repository. I have no problem checking out
a particular commit or tag if I want, I can see commit logs and diffs,
etc.

As indicated by the ';', the first add-to-list neither is, nor was used
in my setup. I was merely saying that “**if** I use the first and not
the others...”. The second add-to-list added the path to tex-site.el as
installed by AUCTeX's 'make install' command. Doing (require 'tex-site)
used to be the recommended way to enable AUCTeX. I take note that this
has changed. I have removed the third add-to-list and am now loading
auctex.el and preview-latex.el directly with `load', as per the link you
provided:

The (require 'tex-site) was from old installation instructions
(pre-2005). These were still working without triggering any warning,
AFAICS. The (require 'tex) was justified by the fact that I was calling
`TeX-add-style-hook' in the provided init file, and `TeX-add-style-hook'
is defined in tex.el.

Since you said that the two RefTeX config bits from the end of the
init.el file I sent were unnecessary with current RefTeX, I have removed
them, which made the error disappear. Thanks for pointing out the error
in the one I had left commented out, too.

Actually, that is:

      (load "~/lisp/manual-installs/site-start.d/auctex.el" nil t t)

But as seen above, since I removed the RefTeX config bits that you said
were unnecessary, it is working fine now. Thanks for your advice!
