The default can be changed in your Emacs configuration. Check out
org-export-default-language.

I checked on of my exported PDFs, and it looks mostly consistent with the
org source from a brief look. The only minor deficiency is sparkled text
from included vector images with text, but I imagine that it is common
and may or may not be a real deficiency.

Do note that Org to PDF export works by first exporting to a .tex file
and then running TeX. As long as TeX makes a decent job with PDF
accessibility, we should be good to go. Just need to make sure that we
pass the correct options to TeX in the generated .tex file.

You mentioned that one of the TeX options is setting the correct
metadata. I am not aware about other required options that can improve
accessibility. If you know any, feel free to share.

Also, you can refer to our previous discussion about accessibility of
documents exported by Org.
