I have a BenQ (710tki iirc) that is like this and I believe it meets all your stated requirements (size, resolution, etc). I’ve been very happy with it.
It's not great for daytime viewing and there's some friction setting it up, but we appreciate that. It's a dedicated movie-night appliance, not something we have on in the background all the time.
Previously, I had a portable project that only advertised 1000 lumens, and it was difficult to use during the day.
I would say that with a powerful enough projector it isn't really an issue unless you care a lot about black levels during the day.
The main issue switching to a projector is figuring out where you are going to position it (different projectors have different throw distances).
More money and more setup, but very worthwhile in the end IMO.
Not that I would forget that tiny detail when I mounted mine. Of course not.
