A little question about stop word and KW density

Hello I would like to know the following:
Let's say I want to rank the following keyword: Best products New York
If in my article I use the following variation:
Best product in New York
Best product [New York]

Will these count as the target KW I'm trying to rank or do they count as a different KW? If I use a stop word inside the KW Im trying to rank will be bad for my KW desnity?

Fortunately Google shows you what it considers a match by making them bold in the results:
Is searched for "best restaurant in new york"

All of these were called out by Google as match words:

best best new york best new york restaurants best nyc restaurants best restaurant best restaurants best restaurants new york bestrestaurant new new restaurant new york new york restaurant new york restaurants new york's best new york's best restaurants newyork newyorknewyork ny nyc nyc restaurant nyc restaurants nyc's best restaurant restaurant nyc restaurants restaurants nyc new york york



Keyword density matches did not correlate but a ton of other things did:
