Actually, Wikidata aims to avoid such judgment calls. As much as possible, all facts (aka "statements" in Wikidata parlance) should have citations to reliable sources. Please see the following page for the relevant discussion: https://www.wikidata.org/wiki/Help:Sources
So in your example, a city can be tagged as being a metropolis if a reliable source states so, such as a government economic planning office.
