How to get communes boundaries of Europe?

Question

I am looking for an up-to-date communes administrative boundraries (LAU) of several countries in Europe (France + adjacent countries). I need it to be quite precise (less than 5m), since I intend to use it to retrieve commune names from a point (bus stop). I was thinking about OpenStreetMap and Overpass Turbo, but the coverage seems to be too wide to be processed, even country by country, here is one of my resquest :

[out:xml][timeout:600]; (
  area['admin_level'='2']['name'='France'];
  rel['boundary'='administrative']['admin_level'='8'](area);
);
(._;>;);
out;

I also found :

• [something interesting] on the eurostat website, but it is from 2013 ...
• [Official LAU], but it not precise enough for my needs
• [GDAM data], but again, not precise enough
