To the best of my understanding your nose is home to countless germs encapsulated from reaching your lungs. If you get a cut inside it, or near it, why would you not ALWAYS get sick since those germs would have a straight pathway into your body?

Because you have a functioning immune system and follow decent hygiene practices, probably. A cut inside/near the nose isn’t that different from a cut anywhere else, pretty much every square inch of you is crawling with all sorts of microbes.
It also doesn’t have much to do with speed of healing.
