In most cases only the first one applies. Rarely ever see monitors that aren’t powered independently. Also sounds like chatgpt wrote this.

They exist but they are rare. Most of them are USB powered small monitors.
If you're connecting your laptop to an external display it's usually via a hub/dock (powering your laptop too, making battery drain irrelevant) unless you're connecting it to a display in eg. a meeting room without connecting power separately and then GPU load matters
I'm having a 15" mobile external monitor for my business trips, which is powered through my laptop. At least for those mobile displays, this is quite typical. Often you just need one USB C convention for power and video
