I was in a similar position earlier this year. Problem was most non smart TVs were business grade and very expensive. Ended up with a Samsung Smart TV but didn’t hook it up to the Internet. Fits my needs and remote is only ever used for changing HDMI devices. It boots up in about 10 seconds.
I’ve always been a power user but never minded Windows until W11. Luckily WSL was a great gateway drug for me and I ended up switching to Linux full-time after living inside WSL for a few weeks.
