Projectors are designed to hang from the ceiling. That is how I installed mine, above the couch. The install is easier then mounting a TV to the wall.
The problem is light control. You want to have blackout curtains and you have to close them every time you want to watch something.
And I might be out of touch with current offerings, but I think the sweetspot for price performance still has not LED options. Only entry and high end. The non-led projectors have a bit more fan noise and expensive to change the bulb, which has limited on-time.
I had my entry level projector for 10 years now and the bulb is still fine. But I also don't watch that much. Paid ~700 EUR. I shitty smart tv with no internet probably also turns on faster. I have to wait ~20 seconds.
The question is what's the budget? Ultra short throw projectors are more convenient because they can be put on the counter in front of where you'd hang the TV, but they're pricey. No need to hang it from the ceiling, or across the room.
Takes an hour and it will hang there for a few years.
I see the use case if you want to move it often though. Though as soon as you bump it you have to move it slightly again. Or let it run through autocalibration etc. For me it's more convenient to hang it to a fixed position where it can't accidently be moved.
