In my opinion, though I don't actually have this option, the killer use case for Thunderbolt (or USB 4) is sufficient bandwidth and a large aftermarket for... Docks. Now, I had a thin 'n' light with just 2 USB-C ports, and I could get a dock/adapter that had power delivery, HDMI, Ethernet and a couple USB-A/USB-C ports. But for high-refresh rate monitors, a proper dock will want a lot of bandwidth. Without that bandwidth, you'll have to pick your compromise on the dock.
