USB-C seems to be hit & miss in general, it not only depends on the connector but also the cable and what's on the other side. I use my M1 with a Lenovo USB-C dock an theoretially it's capable of piping 4k at 60 Hz to my monitor, but in order for that to work I'd need to buy cables that cost half as much as the dock, so I just plug the HDMI cable directly into the Macbook (and am thankful they included an HDMI port at all). Also, you have to know which USB-C port to plug stuff into as they don't seem to be equal in terms of functionality, or maybe it's just the cable? In any case they're not marked differently. But yeah, first world problems.
