Asus XT9 (AX 6e) should do the trick. Wired backhaul or dedicated 5ghz channel for backhaul should work very well for your situation, and more than adequate for 1 GB connection.
I personally have an ASUS AXE7800 as my main router with two XD6 as nodes in an 1800 square foot house (two-story with basement – basement square footage not included in the number).
Also, the XT9 has a 2.5 GB port to connect to your service provider modem, and you can do link aggregation on two of the 1GB ports going to the other router.
You can actually easily do two Asus routers together via mesh because it's essentially baked into their firmware. You don't need to get a mesh system, you can either go for prepackaged mesh or just pick up two routers and set it up as mesh. This opens up options if you look for two cheap Asus Wi-Fi 7 routers, although 66e should work just fine in your situation.
I have the Asus AC56U and AX5400 I use for Spectrum. Great about Asus is the free parental controls (no subscription needed).
Speeds are decent. We use it for COD/Rivals.
For the AX Series the 5400 is my primary router and I use them for a mesh network.
I would just go to the equivalent BE series for the newer higher throughput main connection needs.
Whatever you decide the main router entry point for the ISP should be the best one in the series as it handles all the entry and exit traffic. So you dont want it to be the bottle neck if you spin off nodes later.
ASUS RT-BE86U BE6800 is solid. But if you are looking to spend less the RT BE58U or similar but they wont have the 10GB WAN, only 2.5GB.
counterpoint: I've had both the AX5400 and currently using the BE3600. The only noticeable difference is that the Ring Chime modules stay connected now that I'm using the BE3600 while they would disconnect randomly with the AX5400
I upgraded to the BE3600 because Xfinity/Comcast offered 1.2Gbps service (was at 800Mbps when using the AX5400) for $15/mo less (thank goodness for competition from fiber). To take advantage of the upgraded service, I upgraded the router and modem
Either way, I'm a fan of ASUS networking products, especially the web admin
Asus Expert Router EBG19P seems to have some benefits over Ubiquiti Cloud Gateway, such as more ports. But it's hard to argue the awesomeness of Ubiquiti UI - I love my UDM Pro. Props to ASUS WRT (Merlin) too.
Like others said, just turn off DHCP and WiFi on the ATT Gateway and let your router do the lifting.
Couple with Asus Zen Wifi or TP-Link Deco mesh system in access point model for expandable, upgradeable wireless. Eero won't support this setup (no AP mode).
