First TV since the stone ages

I’ve been using a laptop and my 27” iMac to watch stuff since forever and really only have extensive use of a “new” tv at a friends and that’s a 50” Amazon tv from 2024.
Primary use will be streaming movies/tv and I’ll watch nba games occasionally. I have a GameCube, that I might want to play? Thats honestly lowest priority, I haven’t touched it since the pandemic. It’s going to be in a small living room with west facing windows. I’ll have curtains, but not black out curtains. I was fairly set on getting the tcl qm6k pro, but now I’m spiraling with research overload and am worried I should get something a little better. Price range is ideally under $700
