You would need to get something like:

For my search, I used "usb-c to mini displayport adapter". You should look at the comments and questions to see people's experiences in connecting with the Cinema Display. There are some of these for this product.
The Cinema Display has USB2 so I wouldn't use the hub functionality unless you want to connect a keyboard and mouse off of the monitor - that would require another USB-C port. If you want to use only one USB-C port to connect the monitor and multiple USB ports, you'd have to get a hub that supports Mini DisplayPort and USB-A (presuming you have a USB-A keyboard/mouse).
