I place mine against the wall. It is most convenient this way because the Ethernet and power outlets are against the wall. In addition it means that the remainder of the space is large enough to be used for other things. My wife and I sit in the same room with a table with the 3D printer, home servers, and our various shared workbench tasks in between us. I sit by the window because I like sunlight and looking over the city, and while my wife does too my mood is more mercurially related to it than is hers.

Overall, power and data management dominate this entire arrangement. I have far too many devices each of which draw very little power but demand their own massive power connections. In the end, I will likely just rack most of them to make room for the second child we plan to have.

It's not an issue if your office is so small that no one is hanging out in front of it. :)

My wife only comes in to get printouts and supplies if I'm working, and if she's working (we share the "battle station" by switching out whose laptop is connected to the dock) I basically only go in there to quickly chat and walk around to the other side.

Walking into my office, you definitely see the backside of my dual monitor + audio interfaces + studio monitor speakers (I dabble in music production as well as tech) from the doorway.

I just live with it. I'm on the good side. The few times a day my wife needs to talk to me she just comes around to my side of the desk anyways.

A few scattered thoughts but a board with decoration or art of a similar size could be a nice cover, the other (more building required) would be to look if there’s a way you can fold down/away the monitor when not in use.

You just need a home cubicle.

If you do good cable management it looks good imo. I have a desk arm with monitors attached on their VESA mounts. All the monitor cabling is attached to the mounts and goes into the cable management tray under the desk with everything else.
