I have a CalDigit TS3 thunderbolt dock. it works just fine with my old (2018) MacBook Pro, and my new (2022) MacBookPro. I have 2 27 inch Dell 4k monitors. One of them is connected to the dock via DisplayPort. Another one is connected to the dock via USB-C to HDMI. Works like a charm. I also have my personal 2015 MacBookPro, and I don't really connect that to external monitors these days. If I wanted to, I'd use thunderbolt 2 (mini display port) to display port cables.
