Wrong location / place by GPS - Location Services - GNSS - Maps

There are different types of AGPS, one just using the mobile signal strength and station ids and looking those up in a (local or remote) database and applying trigonometry mathematics, the other one adding WiFi ESSIDs to the game, and I thought the latter one is only employed by FAAMG and the likes. But I may of course be wrong!
Today I tested again, with WiFi and Bluetooth switched off by software. First, I got a very fast pseudo-fix, in Germany, in the south of Frankfurt am Main, and this looked somewhat familiar ...
After some 30, 40 additional seconds, it got a new fix, and it gradually approached where I really was (out in the wild, with no WiFi near me). After about 90 seconds the map precisely followed me. I'd call that very much OK, better than what I expected.
