Recommendations for wired backhaul satellite for RBR50?

I have an RBR50 router with one Orbi Voice satellite connected via wireless backhaul.  This does a great job covering the main floor of my residence.

I have two remote areas that are not reliably reachable via wireless backhaul.  I do have a wired ethernet connection connected physically to the RBR50 in each of these locations.

What Netgear products are suitable to extend my mesh via a wired ethernet backhaul connection?

Thank you for your advice!
