I did wonder if that might be the case.
The 144Hz + USB-C is kinda the holly grail of monitors since it doesn't really exist yet but it's not far off if you don't mind waiting to see how the Eve Spectrum QHD fairs when released around the end of June.
As for the DP the answer is yes unless you have HDMI 2.1 on both ends. However, the USB-C on a lot of monitors also consists of DP Alt Mode and Power Delivery output delivered over the USB connection. To make use of this quasi docking solution you do need to understand what wattage the laptop requires to charge over the USB-C as some monitors output a lower wattage that is only suitable for some laptops and some Apple laptops I think require the higher level of around 100W. That then just leaves sharing a keyboard & mouse between systems which you can do either with a physical USB switch (around £20 for two systems to share a number of USB peripherals) or a software solution if the systems are under your admin control to install software. The only downside I can think of is if you have Ethernet connections available at the desk as this method of docking would only see the laptop either connected via wireless or having the Ethernet cable as a second or third cable to connect depending on whether you choose to go for a USB switch. The software solution for sharing the keyboard and mouse would also require the desktop to be running too.
