I have never tried so complex babel configuration. Should "latex-lang" 
options affect ox-latex in any way besides adding 
\usepackage[...]{babel} and \babelprovide[...]{...}? If not, maybe it is 
better to use

#+latex_header: \usepackage[french,catalan,uppersorbian,bidi=default]{babel}
#+latex_header: \babelprovide[import,hyphenrules=+]{hebrew}

directly and add default \usepackage[french]{babel} based on 
"#+language:" only in the case when babel is not loaded through 
"#+latex_header:". Currently such strategy is implemented for inputenc 
or some other package.
