Very good question!
I looked into the example of “strategy” : https://www.wikidata.org/wiki/Q185451. It exists and has translations in dozens of languages. Of course it refers to the idea of strategy in general, not specifically to the wikimedia movement strategy, but it would still probably be usable for localization of this tag^^
Then of course, tags like “About Wikimedia Space” or “Space feature requests” are too specific.
But general topic like “education”, “research”, “events” or even “indigenous languages” (https://www.wikidata.org/wiki/Q645304) have useful Wikidata items…
I have very little software knowledge so I can’t push the reflection further about specifics, but I feel it could really help with localization !
