I’ve personally had very good results with Ubiquiti Unifi kit. It’s business grade, so not cheap, but highly effective.

The access points prefer to be wired, but have a fall back mesh mode. It doesn’t add much latency, or lose much bandwidth. Furthermore, the access points seem to have FAR better range performance than most home kit. I had a situation where a “long range gaming” access point became unreliable after about 10m. The Unifi LR gets over 50m in the same environment.

Network over Power line adapters can also be useful, and can reduce the number of access points you need.
