I have a Roku box for both TV's.
It gives lots of choices, not all of which are free. I like it mainly for Netflix, Amazon Prime, and YouTube.
I am never bored with TV! Two of my favorite series both just had new episodes added, and when I'm done with those, other series I like will be adding. Movies rotate, so for instance, in my Netflix movie list, today Ferris Beuler's Day Off may be gone, but Super Troopers is back. Netflix and Amazon both work like that.
When we first got Netflix, I had fun watching movies I'd heard about, but had never seen, like Death Race 2000 and Fritz the Cat!
A friend who still has network TV came over. I asked him what he wanted to watch. His favorite bands are Pink Floyd and The Beatles, so I found him a clip of David Gilmour jamming with Paul McCartney. He still doesn't have internet, but now he's thinking about it.
Sometimes I just want to have the TV on while tinkering around the house. I'll find an episode of Mutual of Omaha's Wild Kingdom with Marlin Perkins. Or maybe a favorite from Hickok45, but you get the idea. There is never anything on my TV that I don't want there. Oh, the occasional YouTube commercial, but that's a small to pay for the TV freedom I enjoy.
