Drupal 8 Global FIlter

I have questions that I cannot find answers to on the internet 

There is a project where it is necessary to divide all pages by regions 
example.com/region1/ and then categories

How to implement this? At first, I thought to make region as a category, but I have only 600 categories, and it turns out 80 regions × 600 categories = that’s a lot. Then I thought—there are languages on the site, and they are somehow implemented, so I need to implement regions like languages, so that when selecting a region, you can navigate the site further, but the information should be strictly for the selected region.

I read somewhere that for such tasks you need the Global Filter module — but I have no idea how it works; for Drupal 8 there is only an alpha version of this module from 2013. I think it’s not worth installing.

Could you suggest maybe some other option?
