I already do this, and it's wonderful. I had to get a monitor that was way too big though to find one that had all the ports I want and which could supply enough power back to the laptop, but I assume smaller monitors are getting it by now too. Still though, it's well worth it if you need a new monitor to wait for one that has all your preferred specs and also does USB-C, I don't think I could go back.

I plug in my laptop and the monitor comes on, my keyboard and mouse start working over USB, my speakers start working because I turned the builtin soundbar off and enabled the in USB-C/3.55mm DAC that's also built into some Dell monitors, and even my printer and a synthesizer that I use as a practice (piano-)keyboard are are ready to go.
