We've replaced most of our RPi units with the Beelink SER MAX 5 or whatever at $300ish price point; just too good of a deal (and all of its hardware works with Linux, unlike some other MiniPCs).
But we still use RPi4/5s when we want the ecosystem of the RPi, particularly around the GPIO stuff. Typical things include environment monitoring such as lighting and air quality - super simple plug-in devices that easily interface with Raspbian and the GPIO system.
Power draw is much lower on the RPis which I think is relevant for some people; not really us. But that's a pretty valuable use case for those who are shipping battery-backed devices.
