Question Upgrading My Apartment Network to 10Gbps Ethernet and Wi-Fi 7

[Snick2040]

I would like to upgrade my apartment's home network to 10Gbps Ethernet with Wi-Fi 7. Even though it’s just an apartment, every band and channel seems to be taken. Fortunately, I already have Ethernet running throughout the apartment. I recently bought a Fluke to test the quality of the Ethernet runs.

All the Ethernet runs terminate in a cabinet in a utility closet. I don’t need Wi-Fi in that location, so I currently have a router there with Wi-Fi disabled. The router connects to two access points located on either end of the apartment and to Ethernet switches placed around the apartment. I’m so grateful for Ethernet because I hate Wi-Fi.

I decided to try out a Netgear Orbi 970 with a satellite. I don’t plan to use the mesh feature (again, I’m not a fan of Wi-Fi). My plan is to move the cable modem to where one of the current access points is located. I’ll replace that AP with the primary Orbi 970 and run a 10Gbps backbone from the Orbi to the utility cabinet. In the cabinet, I’ll install a 10Gbps switch to distribute the connection throughout the apartment, including to the satellite Orbi at the other end of the apartment.

My Questions​

1. Is there a better solution? Are there any alternatives to my current plan that would work more efficiently? Like keeping a non WIFI router in the utility closet.
2. Will this setup introduce noticeable lag? Specifically, would having a 10Gbps switch in the utility cabinet, instead of the main router, cause any noticeable latency from the main 970 to the satellite?
3. Switch Recommendations: Should I use a managed or unmanaged 10Gbps switch in the cabinet? Are there any specific models you’d recommend?
4. Wi-Fi Roaming: I’d like seamless Wi-Fi roaming throughout the apartment. I’m not sure if my current setup supports this anyway or if the 970 would either in the scenario I described.

I know that 10Gbps is overkill, I only have a 1.2Gbps internet connection, but I want to future-proof my network.

Thanks in advance...
