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>
