I think you’d need experimental research with randomization to several languages and this would be very costly and possibly inethical to set up.
You just need to have an area where different schools have different curriculums and there a lottery mechanism for deciding which student goes to which school.
That deals with the costs but I doubt consent would be easy to obtain unless the schools are very uniform in quality/status and people don’t have preferences about which languages to learn, hence the possible problem with ethics. Schools have preferences too, quality schools want quality students.
There are multiple ways you can solve the problem of who gets to go to the most desired school. You can do it via tuition fees and let money decide who goes to the best school. You can do tests to have the best students go to the best school. You can also do random assignments.
Neither of those are “better” from an ethical perspective.
If you let money decide or do tests you lose the statistical benefits of randomization. I don’t understand how you see no ethical problem in ignoring preferences or not matching best students with best schools, perhaps I misunderstand you.

Yes of course, you need the randomization.
If you want an equal society that it’s impotant that poor students also get good teachers.
