That monitor has the following video inputs:
- DisplayPort
- Mini DisplayPort
- HDMI
- Dual-Link DVI
I would suggest getting a USB-C to DisplayPort adapter cable, or a USB-C to Mini DisplayPort adapter cable. (Mini DisplayPort and DisplayPort are the same except for the physical size of the connector.). Your Mac generates native USB-C (DisplayPort) output, so this involves the least conversion.
I would avoid DVI. You would need to be careful to get a USB-C to dual-link DVI adapter (most adapters are single-link) and a dual-link DVI cable. Back in the days before USB-C, the Apple Mini DisplayPort to dual-link DVI adapter and others like it had a reputation (earned? unearned?) for being a bit flaky. There simply is no point in paying more to connect in a less reliable way unless all THREE of the other inputs (DisplayPort, Mini DIsplayPort, and HDMI) have already been filled up for other computers or video sources.
You can get USB-C to HDMI adapters and adapter cables, but I wouldn't bother with that unless the DisplayPort and Mini DisplayPort inputs are already spoken for.
The monitor also has a USB-A hub. If you want to use that, you'll need to run a separate USB data cable.
