The category I ended up targeting is portable monitors aimed at the business laptop market. These are slim, have a kickstand for support, and can receive data & power over a single usb-c. Not sure about product marketing restrictions on HN so I won't say the brand. But it's a 14" portable monitor from a long-running business laptop brand.
If you want this for a non-laptop scenario, my advice would be to pay very close attention to the types & versions of connectors on the devices you're trying to connect. My gaming desktop didn't have the exact right usb-c port. That sent me into the world of 'weird' cables and lots of debugging to finally get it set up the way I want.
