It's nice to have the fastest Wi-Fi possible even if your upstream internet is slower. Sometimes you want to transfer files locally between devices, or run backups etc. Faster Wi-Fi here can make a huge difference to those tasks.
I have found that higher tier WiFi aids local game streaming significantly, but most of that benefit seems to be the 6Ghz band that you get with WiFi 6E.
