Birkir, I feel that your "guide to our site" should be a standard
feature of all sites. Include one section on things that work ("We do
use headings to achieve proper semantic structure, so you can rely on
them for fast navigation of our pages.") and another on things that
don't work or barely work ("We do not have captioning for our videos,
but we have provided a text transcript and audio description for each
one. The first link immediately after each video is its transcript. The
second link is its audio description.")

Yes, it takes work, and it takes a coordinated effort in building the
site, but it seems to me that your experience demonstrates that users
would appreciate these tips.

Either that, or distribute the Powerpoint files with a little hand

In general, I wonder if any such guides exist and if it might be a
good idea to compile them.
Powerpoint with Jaws/Window Eyes, Google Docs with Jaws (an exercise
in frustration) etc.
I've done the screen reader specific instructions for a few minor
software things and users have very much liked them.
I was asked to write up a little guide for screen readers as a temp
solution for a web site that was not overly accessible, but going
through an update.
The guide explained how to do certain things on the site, step by
step.
I've never seen anyone else try this, and it is true that web sites
should never require user guides for how to perform certain things,
but it was actually quite popular with the users of this site.
They felt they learnt something new with their screen reading
software.
I guess I am not sure where I am going with this but, generally, I
think trying to push your users, teach them something new, ease them
into using Powerpoint, may be a good thing to do in some situations,
mostly educational settings.
It all depends on your audience.
