I did not say photosite density, I said resolution -- those are two different things.
Not directed at you, but in general I’m a bit perplexed by the (seemingly now) notion that cropping into higher resolution images is a substitute for using longer lenses. In fact, sometimes we do end up having to do that and we can get good enough results — though they won’t be as potentially good as putting the appropriate lens on the camera and using the full image area.
It's not perplexing (to me) that people would crop in to a high resolution image if it yielded "good enough results" for their use case. There are lots of reasons why someone would settle for good enough over purchasing and using a lens for a single specific task.

In the context of the post I was replying to, that is a distinction without a difference… since photosite density is the only difference.

Does 40mp get you more resolution? Yes but probably not as much as people tend to think on here. Should come out far ahead concentrating on lenses, getting closer
150 yards can mean all sorts of things. Really ought to use the 50mm and crop to 500mm or more, to see if it's enough
The M4/3 system is built around higher pixel density and shorter focal length lenses. It doesn't perform as well as larger systems but it could substitute depending on one's need for quality versus price, noting that some M4/3 lenses are very expensive.
In the film days it was known that finer grain film could be enlarged further and cropped more. I don't see why this is different to pixel density.
Choose the 500 mm f/5.6. Add a 1.4× teleconverter if needed. Use a higher‑megapixel body for cropping. Build a small blind to get closer. Test framing first with your 50 mm lens and crop.
