I’ve been looking for a Wi-Fi 6 router with 10GBe ethernet ports too.
Its kind of silly to have wireless that is faster than the wired options. One use case is that I want to store larger files on a NAS but I don't want throughput to randomly drop such as during large image backups and restorations to a cloud server.
WiFi specs refer to the maximum theoretical link-layer rate in perfect conditions. The actual amount of data (not link-layer bits) transferred is less than the headline number.
In the real world, 1G ethernet isn't going to hold back a WiFi 6 router. The only exception might be a multi-radio WiFi 6 AP that is within several feet of WiFi 6 clients on both radios.
I'd be surprised if it is much of a restriction in real world use cases. Accessing my NAS over 866Mbps WiFi[1] caps out around 60MB/s, the same devices over gigabit ethernet hit around 120MB/s (the NAS delivers around 650MB/s over a 10Gb link).
[1] tested with multiple client/router devices, in close to ideal circumstances (few feet line of sight between devices, no other devices active on the network)
802.11ac from Google Wifi maxes out at around 300 mbps for me (on gigabit internet. for one device). Not sure on your setup, but it does matter how many streams your Wifi network adaptor has.
The advertised speed of your router usually doesn't mean much, as it usually implies the maximum concurrent speed available, rather than how much one device can use.
