The FCC has published its Pixel 6 and Pixel 6 Pro listings, which spans six devices. All models support Wi-Fi 6E connectivity, a jump from the Wi-Fi 5 coverage that the Pixel 5 and Pixel 5a offer. A UWB chip will not be available across all models though, and could be confined to just the Pixel 6 Pro.
