I have always viewed Ubiquiti and UniFi as serving only the business and enterprise market, not consumer grade individuals like me. I have gotten frustrated with the Netgear and TP-Link grade of WiFi equipment available to the consumer customer and have now ventured into UniFi. My main challenge was just getting a single SSID to work around a large home. Mesh WiFi held a promise until I found out that they really aren’t that good unless you are using backhaul wiring. Companies have been using single SSIDs for decades and that’s where the solution was.

I've gotten a lot of mileage out of Ubiquiti gear in SMB space, but enterprise it is not. Ruckus, Aruba, and to a lesser extent Cisco (Meraki) own that space. I wouldn't trust Ubiquiti gear to handle the densities that Ruckus gear can, for example.
For your home frustrations some cheap Ubiquiti gear and spending the money to cable all your APs will do what you need.
I used to do a wireless mesh with U6 (wifi 6) and I 100% agree with you. But with WiFi 7, everything changes. WiFi 7 wireless mesh is actually faster than hardwiring (mainly because my second AP is connected to a 1G flex mini). A WiFi 7 mesh can actually exceed 1G (using Wifiman, I get about 1.5G). Meshing with a WiFi 7 AP works great for me too since all my devices are only WiFi 6 compatible (for now). Highly recommend replacing your APs with a U7-<whatever you want>
