The only thing I'd stay for using a Dell monitor is: If you plan to use it with a Mac, be sure that they are compatible. Dell has a fantastic return policy, which was lucky for me, because the first USB-C monitor I ordered from then had a pretty terrible image when I used a Mac. It's no fault of Dell, it is Apple who are rather picky with displays.
If you just need the one monitor, Dell has some great options. I can just have the one cable to my laptop, everything else is wired to the monitor and works great.
I was looking for a dock for a MacBook M1, and was going to buy some $300 box (and there were no absolutely reassuring reviews for any of them) and was compiling the similar looking table - when I noticed that my Dell U2721DE has a sound jack… and an Ethernet jack - and does not have any problems docks have, like overheating.
So the Dell monitor is connected to 3 computers now, it switches sound depending on the video source (!) : USBC, DisplayPort and HDMI all pass sound to my headphones. And Ethernet stays with USBC box - exactly what I wanted. I still need a keyboard/mouse switch but overall “Display as a dock” setup turned out very good for me.
I've had the poor image quality problem with Macs and Dell displays for ages. My go-to fix that usually works is to generate a custom EDID profile for the monitor that lets it negotiate to use RGB signalling rather that YPbPr 4:2:2 crap. I think Apple does this on purpose. LG displays seem to work out of the box.
I Googled "Mac EDID ruby"[0] to try to find the script that I'd found and used.
