Hmm. I feel that most users will default to these, and default :font
will make things easier - without default, users will have to lookup
default fonts anyway. But let's not argue about this. I will compile the
things we see differently later and ask for user input in a separate
thread.

The next thing I find important to have is some way to define fonts
inside Org document itself, via keywords. We can already do with
file-local variables, but having a keyword setting will be idiomatic for
org export.

The rough idea is something like
#+LATEX_FONT_MAIN: Font name
#+LATEX_FONT_SANS: Font name2
#+LATEX_FONT_MONO: Font name3
#+LATEX_FONT_MATH: Font name4:<font props>

WDYT?

Apart from this, I think that we need to provide special handling for
#+begin_language <lang> ... #+end_language special blocks to avoid the
awkwardness of using different way to specify language for babel vs
polyglossia.

No other items in my priority list.
