I got a Sony Bravia, but made sure never to enter the wifi password into the TV directly, but rather hook up an Apple TV and only use that.

This way I still have a "dumb TV" (apparently impossible to get now).

Second option would have been to get a projector.

I have a Sony Bravia, configured it on WiFi, and created a new gmail account to use with the built-in Android TV system.

It seems fine: no ads, nothing spamming, and it has an option to not share any data, which presumably (!) it pays attention to.

I started with the no wifi plan for my Sony. They would put popups on screen warning me that I wasn't connected to the internet, even when using a streaming device or blu-ray just often enough that they got me to connect it to the internet. I don't use their apps and turned off the data sharing. I haven't noticed an uptick in personalized ads anywhere. If anything, my Facebook ads are worse than they were before. Just a bunch of crap I'm not actually interested in.
