There is more to life than just HDMI, that’s for sure. It is well worth reading this linked article before buying any new monitor or graphics card.
Something interesting I learnt is that with DisplayPort there is the possibility of MST or Multi-Stream Transport where you can daisy-chain multiple monitors together with DP cables using only a single port on your GPU.
Also, it’s important, as it is with USB-C cables, to get HDMI cables that match the version of HDMI that the monitor supports.
