I guess I am a little confused. What advantage do these monochrome conversions have over just shooting in RAW and processing as a black and white image in Lightroom?

Actual resolution (it's similar to pixel shift as all the sensor pixels are used, a normal sensor needs four to make up one pixel) and low light performance. Use a search engine for more detailed info.

I didn't realize that's how it works, thank you.

If you use FB I can provide some video samples

Thank you but I avoid FB.

TO add more to the discussion - the typical way a camera creates images is to interpolate the color filter array data into meaningful images by demosaicing (https://en.wikipedia.org/wiki/Demosaicing#:~:text=A%20demosaicing%20(also%20...20array%20(CFA).) the data to guess at what colors are when they don't actually line up with the correct pixels. Essentially it looks at data from the other sensor sites and creates a best guess. A true monochrome camera doesn't require this and you can simply go right to the brightness values for each pixel ignoring the rest. This has implications in detail level and accuracy.
