I added your link to What options are there for fonts? where I asked a very long time ago which options we have for MonoGame
I don’t think there is very much more to do apart from adding usings for the namespaces if there are ambiguous and / or missing in the solution / project(s) code.
Maybe the project you have found is better anyway? I don’t know which technique is state of the art so to say. Maybe somebody else can tell if this is the way to go. But even if not then if this is what works for you then you don’t need something else.
The demo from the MonogameDistanceFont is pretty nice. Interesting topic, I mean font rendering unfortunately I don’t know much about it 
And the part with the GraphicsDevice is just one line where this change is necessary.
