Hmm. What aspect of caching do you want us to document?
FYI, Org mode has been doing various forms of caching since
forever. Recently, we just employed a bit more regular API and
introduced one more kind of caching - parser cache. In addition to the
previously existing image cache, publishing cache, ID cache, clock
cache, etc.

I believe that this particular problem has been solved in
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=c8f88589c
It is a part of Org 9.7.
