I would go for an OLED. LG, Samsung and Sony all make good ones. I love my LG C3 and the newer C4 is also great. You could even find a C3 in a larger version so it fits your budget. the more expensive G4 is also there.
You can use it as a dumb tv if you reject the terms and services. (at least on the european versions)
Samsung is also good but lacks dolby vision and they seem to have a particular color profile that people seem to either like a lot or dislike.
those screens tend to be overpriced for home use and their image quality is not the best since the signaging priorities are different.
I’m not sure about Canada, but in europe you just need to reject the terms of services of the TV OS and you can use it as a dumb tv.
