Wifi performance is lots of details - channel width, signal level, interference, plus meshing can halve speeds each hop. To be "wired" fast you need clear space, wide channels, and clear line of sight to the AP. Wifi7 brings some channel width magic to help, but you can get decent throughput on wifi 5 or 6. If you need to do lots of large file transfers, wired is the way.
Also I very much doubt lots of 100gb+ setups - 10gb is affordable if still not cheap and requires wired connections.
If you want to verify your server isn't the bottleneck you'll need a wired connection. I cap out at about 3.3gb/s to a raid10 SSD write cache on 10gbe (verified 9.8+gb/s via iperf3).
