Thanks, the list is longer than I remember. Looks like they have added some countries.
In most cases, switching the region will add you some apps that you don't really need. As far as I have tried FR is the most bloatware-free choice. When you select it as the region nothing changes anywhere. (except you get the face unlock).
India is good btw for the fact that you get the wallpaper carousel, themes app, step counter etc. No other region offers that. It's the most you can get out of Poco. Alas, you get India-related content in the default browser, if you use it, Indian festivities in the calendar, and some apps that make sense only in India. If you don't mind living with apps you never use I'd say India is the region to select because you get more this way.
If you want to change the theme, switch to India, open the Themes app, select one you like, download, apply and then you can switch the region back to anywhere you want. The new theme will appear as one of the 3 offered.
