People here will absolutely hate this because "Google is evil" but I use a Chromecast and I love it and think it's the best option for your use case.

You select whatever video you want to play on your phone or computer and "cast" it to the TV and the video then plays on the TV. There's no suggestions, no promoted content, no upsells, and no ads. Beyond that, a big advantage is you don't have to navigate clunky UIs with a remote, Chromecast barely has a UI at all. When you aren't casting anything it just shows a random picture (usually landscape or cityscape) and the current time.

Another feature I really like and use all the time is the ability to seamlessly switch the TV I'm casting to. Useful for times I start watching something downstairs and then I wanna finish it upstairs.

I also like my Chromecast.

It's ok, I guess, if Google has all your data already anyway.
