Smart T.V. Privacy Overview?

I'm considering buying a new TV. There's plenty of posts about trying to find dumb TVs, comments like 'just don't connect it to the internet/network'.

What surprises me is that there isn't a good overview of (popular) TVs or brands with basic information, answering for each TV:

• Can you use it as a basic TV by choosing not to enable smart features during setup?
• Can you opt out by just not accepting a bunch of agreements?
• Does it have a camera and/or microphone? Where in the device are these? Is there a physical disable switch for microphone?
• Does it nag when not connected to any network?
• Does it have higher than normal power usage when not able to phone home?
• Has it been discovered to connect to public WiFi networks? Does it have the (theoretical) ability to connect to 5G mobile networks?

And similar.

There are extensive lists with a lot of detail about VPN services but nothing like that for TVs. Am I ignorant of a good source, or does this just not exist (yet)?
