eh I've got 802.11be @ 6ghz at home (u7 pro AP and QCNCM865 client) and it is truly impressive, but I only notice the difference once every 1-2 years when I'm transferring a full-disk image over the network for backup. We've long passed the point where the speed improvements matter for daily usage (browsing the web, streaming video, remote desktop, installing updates). For those use cases, you wouldn't notice a slowdown on 802.11ac and I'd argue even 802.11n would be fine.
The one exception I can think of would be video content creators since they end up with large amounts of raw video that would benefit from transferring at much-faster-than-streaming speeds.
And I guess steam downloads if you don't plan ahead at all, but if I'm planning to play a game later, I'll tell steam to install it hours or days in advance.
I often have to transfer large files in LAN. 802.11ac and 802.11n definitely enough for most of the time. I often have to transfer large files between machines in LAN, with 802.11ac makes you remember that it's wireless, while 802.11be makes you forget.
I have the same setup for a framework main board next to the AP, and it's reliably faster than using their usb-c ethernet extension card.
