If you want “solid Wi-Fi performance”, go with a prosumer setup such as Ubiquiti UniFi or TP-Link Omada. You would wire APs as needed to provide coverage in the house. Anything less - including mesh, and wiring mesh, is going to be less than what you stated you want. The only advantage to wiring mesh (which makes it not mesh) is the management of the network (and both UniFi and Omada are centrally managed when you have the requisite controller. To me, it’s pointless to be spending money on a system that where you’re going to disable the whole reason it’s marketed - the mesh (which is wirelessly uplinking). Cabling access points and wiring as many of your devices as possible is where the best performance and reliability comes from.
Wifi 6 only helps with client devices that are wifi 6 compatible (or for mesh wireless backhauling that is also wifi 6 compliant). It does not help any previous (wifi 5, wifi4 etc.) client protocols. However - wifi 6 is becoming ubiquitous and you may not be saving much money by looking for wifi 5 deals. Or, in other words - it doesn’t hurt to have wifi 6 devices.
Ubiquiti UniFi or TP-Link Omada - both prosumer, a step up from consumer stuff and especially mesh. Both are centrally managed, multiple APs and switches are a breeze. If you’re setting up VLANs later you will appreciate the control. Seriously, if you’re wiring, no need for mesh stuff.
