If you are connecting the hue plugs to your hue hub, then they will not serve as repeaters for Hubitat. They can be directly connected to a Hubitat, or you can run them via Hue. Either way, your mesh looks fine.
My guess is that your issues are driver related with the new Aqara sensors. Have you tried one of the community drivers? You might want to try a custom driver ([RELEASE] Aqara / Xiaomi Motion Sensors driver) to see if that works.
