I bought a used magic trackpad 1 to use on Linux. It works quite well out of the box including multi touch capabilities but sometimes if you do a lot of movement in one go it will lag behind. The newer ones can be used wired and use higher Bluetooth versions so that’s hopefully not an issue.
One noticeable limitation for all is that they run at 90 Hz which is noticeable on a 144 Hz screen, but there aren’t really alternatives as far as I could find.
