"In fact in general it seems anti-immigration/foreigner stances are almost anti-proportional to the number of immigrants/foreigners a person might encounter during their day."

That is an egg-and-chicken question. "White flight" is a thing and people who moved away from ghettoizing cities/neigbourhoods into the surrounding suburbia will likely vote against further immigration.

But that's typically not happening either. I fact usually the opposite happens, the urban areas with lots of immigrants get gentrified, because everyone wants to live there.

On top of that, we are now seeing that outer suburbs which were guaranteed winning electorates for right parties are now becoming more and more left leaning because young urban dwellers are moving there because they can't afford the cities.

Show me the evidence for "white flight" it certainly doesn't happen in most European metropolitan areas (the map of the French elections certainly didn't show that any of the areas surrounding the big cities were right leaning, in fact like e.g. Sachsen and Thüringen, the regions in Germany with the highest support for right wing parties, experience lots of people leaving, not moving there). That's one of the reasons why cities have become increasingly unaffordable.
