USB-C will work fine for these things. I've found it very reliable. But will the dongle be a nuisance for you?

If you're only going to be using them in one place (e.g. your home office) then go for a dock - it's nice to have everything connected with a single cable and a number of monitors have suitable docks built in these days.

If you'll want them on the go then yes, I'd at least look for something with the audio and hdmi ports built in just for the convenience factor.
