I recently picked up a ThinkPad E14 gen 2 with a Ryzen 7 4700U for €200. The gen 3 version has Zen 3 CPUs. The Wi-Fi card is M.2 A+E compatible, and although it shipped with Intel Wi-Fi 6, I upgraded it to a 6E card for €20. It is a cheap but nice-cheap laptop that seems like it matches what you're looking for.
