I doubt that we can easily catch option clashes like this.
People can customize things arbitrarily with #+latex_header, and we
cannot catch all the possible problems.

What we might improve is displaying compilation errors in a popup buffer
rather than almost-invisible message in the echo area.

Agree.
For multiple languages, see the discussion in
https://list.orgmode.org/orgmode/878r9t7x7y.fsf@posteo.net/

> 1) more docs on #+language

If you have ideas how to improve the manual, feel free to share them.
