Deco X55 Pro

I have a near identical set up to you in that about 2200 SF and version FIOS. I have three TPLink x55 pros (WIFI 6) about the home and have IMMACULATE coverage. I know it isn’t in your list but would still highly recommend. That said, if the x55pro is sufficient, I think any of your listed options would do even better. So my input is that you can’t really go wrong

I've been seriously considering that switch myself. I jumped into this sub b/c I a asked to look at some networks using older eero setups. Found it so dumbed down that it was very hard to troubleshoot but coverage was total a$$. Once I got it running correctly, I was actually pretty impressed with the performance. especially the mesh backhall. I currently run a upper midrange 6+ deco system because until I see how well eero worked, it was by far the best I'd used. But the small business class Omada systems I've built have become my preferred standard. Just, I haven't played with mesh function on Omada and have no idea how capable it is it isn't. The other part of the equation is the cost of ownership. At the pricing I've been looking at for eero units supporting 6ghz - it's almost a toss going with it or eero when I upgrade my own home setup. Curious, anyone have any suggestions for a 6ghz eero setup with 4 APs ( meaning a master and 3 extensions via mesh backhall)? The house setup is a pain, 2 floors and backyard, and the ftth is on one side of the house dead center (where I put my main AP due to difficulty accessing above it below for extending Ethernet) but having the 2nd AP just past halfway across the width of the home, yields mediocre performance and trying to run the 3rd downstairs below the 2nd leaves 2.4ghz devices struggling no matter how many optimizations I run. Thinking maybe a 4 AP system may be required to improve things at 2.4 so my TAPO cameras don't struggle so much.

Arris Surfboard and TP-Link Deco X-55.  I own both and they have been bulletproof. 

I have a mesh consisting of 2 Deco X55’s. Each has 3 ethernet ports. Unit #1 is connected to the Optical Network Terminal (Fidium is my ISP); Unit #2 is connected to Unit #1 via an ethernet cable that’s built into the house. My security system hub is wired to Unit #2. Now that you mentioned it, I’m going to plug in my laptop to Unit #2 and test the speeds to/from.

A Deco x55 AX3000 2 pack is $100 or less and would probably be a big upgrade for you. We set this up for our parents. And it supports ethernet backhaul if you ever decide it's worth running an ethernet cable instead of using mesh.
