My work laptop has
2x USB A
1x USB C
1x DisplayPort
1x VGA
1x Ethernet
1x SD card reader
1x Power (proprietary)
1x Dock port

I could stand to lose VGA, but wouldn’t want to give up anything else, especially the real dock – USB C docks are much less convenient when you’re coming and going a lot. Perhaps more importantly built in WWAN is a must – I just don’t see why it isn’t more common on high end consumer models
