If you know about a nice implementation of such selection I could use as a reference, feel free to share.

https://wiki.debian.org/DebianGeoMirror is one such implementation
(self-hosted/-managed)

Another one I've seen seen is https://github.com/etix/mirrorbits. It has a lot of fancy features and is used by several large projects. Several feature stand out to me:

• Support for partial mirrors, so you can have smaller mirrors that mirror the popular packages and leave the older versions on the main archive;
  
• Disabling broken mirrors automatically;
• Weighting mirrors based on bandwidth; and
  
• Load balancing between mirrors in the same geographic region.

It's probably worth considering.
