For the sake of anecdata, I found that even the Caldigit docks fail to work on the Intel Macbook Pros (I only have a single data point about the M1s and they didn't work there either). When I hook even basic things like my keyboard and mouse up to the USB A ports, things work for about 20 minutes or so (varies widely) and then the USB A ports go dead requiring a reboot to restore.

This is a known failure mode, but it doesn't hit everybody. It is solely an Apple software fault as older OSs do not exhibit it. I really wish I knew what the issue was.

On the plus side, I found this so infuriating that I finally threw all in and switched to Linux full-time (Lenovo X1 Carbon with a ThinkPad dock) and haven't looked back since.

Side note: practically every thunderbolt dock I have works fine with every x86 laptop I have running either Windows or Linux (including the Caldigit!). YMMV.
