I’ve used it a lot for reports when I went to university, but for short notes I would prefer markdown and for a few pages or documents where formatting is trivial I still find it easier to use LibreOffice or word. I find it likely that most high schoolers would find it easier to use word for any document than LaTeX which they probably have never heard of and would be unable to get support for unlike word which is commonly provided by the school. So while understand where you are coming from, I don’t think the students are in a situation where that would be a plausible solution. Especially due to the many pitfalls and the learning curve you have to get through for using LaTeX as efficiently and for as complex formatting as they already know how to do in word. LaTeX has a way higher ceiling of quality, but the floor is also much lower for those new to it and without the drive to learn it.
