I've been doing some manual importing, and have found that in the vast majority of cases, when different languages' Wikipedias have different coordinates for a location, the coordinates that are most accurate are the ones in the language that is spoken where the location is. For example, some of the first locations to have their coordinates brought over to Wikidata were some train stations in the Netherlands. The Dutch and English Wikipedias' coordinates differed, and the Dutch coordinates were right every time. One English Wikipedia coordinate was even for the next station down the line, over an arcminute away.

Therefore I think that we should coordinates for locations in Germany from dewiki, locations in Spain from eswiki, locations in the Netherlands from nlwiki, etc.

I think it should be possible to just import them as data with
different sources.
If a coordinate pair is the same over multiple Wikipedia then you have
more sources, see for example the property occupation:politician
here[1]
