I believe that the difference between sitting down and reading a book for an hour vs. browsing the internet is _exactly_ what makes books so valuable.
You're right, books are a lot of effort. However, they teach something that internet articles & videos don't, and that is delayed gratification.
In the digital age, everything is fighting for your attention and it is getting harder and harder to actually focus on anything. Clickbait titles is perhaps the most obvious manifestation, but you can see it in videos as well - many popular videos are edited in a specific way (no pauses between sentences, cut after cut after cut) that grabs your attention as often as possible.
Books let you practice tuning all that noise out and focusing on a single task for a long time, while still providing entertainment. For a knowledge worker, to be able to focus at this level is a very valuable ability!
Deep Work by Cal Newport is a non-fiction book that goes into more detail about some of these ideas concerning focus in the contemporary era.
Another great non-fiction book that really couldn't be presented in another medium is "The Righteous Mind: Why Good People Are Divided by Politics and Religion" by Jonathan Haidt. The Righteous Mind is not an easy read because the ideas presented are complex and wide-reaching. It takes a lot of time to go through and digest, but it is definitely worth it. The Righteous Mind has had perhaps the most impact upon my understanding of humanity and politics out of anything I've ever read.
If you want to see what it's like to read for fun, check out the Broken Earth trilogy by N. K. Jemisin - this is probably the best pacing I have ever experienced in a fantasy series.
And if you think science fiction would be more your thing, try to to take a stab at reading Dune by Frank Herbert. This is a sci-fi classic that essentially codified the genre, and some of the ideas in the series are what made Star Wars the phenomenon it is today. I think you can't get better proof that books can stand the test of time than this!
