Yes, there is two aspects. What a tag means and what people think it means ;-)
Both on Steam and Itch, the people chosing the tags are not reliable on the meaning of words. You would need curators for that. So tags genres mentioned on professional articles about a game might be more accurate.
Skimming such articles, Blue Prince seems to be a mystery puzzle rogue-lite. Bordering on deck-building, without being one. Of course the 3d immersion is missing from your game.
For strategy one might read the wiki article about it.

Having strategical thinking involved is not enough. It would be like calling a game point & click, because you can point at things and click them. Or calling a game a visual novel, because there is things to see and things to read.
But I have not played your game. Nor the inspiration for your game. Chess is a strategy game. The strategy game. You command units. Strategy is the skill used by a commander. A game with a single acting entity feels wrong to be named a strategy game. Yet I even found an article mentioning "strategy" to describe Blue Prince. I disagree ;-)
