Best 50in with wide viewing angle?

I’m looking to get a 50 inch 4k TV for the living room. This is not my main viewing screen but I would like it to be quality. I noticed the tcl qm doesn’t go that small. I would go bigger but it’s fitting in an entertainment center with a space that’s 45” wide and 29” high. I’d like a wide viewing angle as the living room is quite wide. Also wouldn’t mind something sturdy because my son will likely touch it at some point.

Any help is greatly appreciated. Thanks all!
