The best quality streamer I have found is Apple TV+ which seems to range in the 25mb/s range for 4K content.

They need WiFi 6E to make me consider upgrading.

You would be best and most simply served by two devices.

Order a Firewalla Gold (or gold plus) and then any WiFi router or mesh system that you want, set it to bridge mode. Eero hides a lot of their stuff behind a $9.99 subscription, but the Firewalla does it better anyway.

You did not mention budget, so if money is no object I’d grab a 2 pack Eero 7 Max or a three pack Eero Pro 6. I would not recommend the 6E or 6+, check the reviews.

You will be set for years.
