How do you get the fiber through your walls? Isn't the appeal of PowerLine and MoCA that the cables are already there?
Lawrence Systems has a good demo of how they do it (wall fishing) commercially:

Yes, that is the appeal. But that doesn't mean it gives a better/faster long-term result.
If you don't have access to either there is a drill bit on a 40-80 inch flexible shaft. You cut a hole in the wall for the box you'll mount the ethernet in and then use it as access to drill up/down/sideways behind the wall.
