London and Paris have fairly uninteresting airspaces from an aviation standpoint. Flat, not many airports. If sightseeing is your thing, there are better ways.

I wonder if it’s based on usage from previous versions of Flight Simulator.

I'd say the approaches into Heathrow (as least on westerlies) are pretty iconic, being that they tend to turn final over central London.
