Look for a ThinkPad T480, I recently bought and upgraded one - much to HN's rage: https://maxrozen.com/replacing-my-macbook-m1-with-thinkpad-t...
On Ubuntu, there's a "hardware enablement kernel" package, linux-generic-hwe-22.04, that's just the kernel from the latest Ubuntu back-ported to the LTS version. I find it tends to fix most issues with newer hardware. Maybe PopOS has something similar?
Anyways, I found the MIMO in wifi 6 was better enough that I even upgraded another old laptop I have with an AX210 I found for $14.

Also, the latest Intel iwlwifi firmare is slowly evolving to address crummy AX200 speed issues that Windows does not suffer. On one of my laptops the AX200 is all over the place speedwise, but running wavemon shows it stabilize in the 600 range of rx and tx after awhile. Here's hoping for progress with that firmware on Linux.
