The "original" XTEINK X4 (not pro) has a USB-C port - that's explicitly why I bought it. It looks like it is out of production now. The good news is they are a proven, very popular device (it's just an e-ink display glued to an ESP32 with good third party support) so this class of device should be available on AliExpress soon if not already.
Just to point out the usb-c on the original x4 is for charging only.
Also firmware updates (on the non-locked variants), no?
What other potential uses are there? Uploading books without WiFi is the only one that comes to mind.
