Many of the things you mention, crossing out, circling, I do not think of as actively engaging with the material, which a quick skim of the underlying research pointed out in the TFA (or maybe an earlier 2017 paper of theirs) requires using the fine motor control of actually writing. Writing marginalia is good for the brain; if you disagree, write out why, if you agree, write your reaction. Highlighting, circling, crossing out are mere consumption and only useful for finding passages later, not engaging your brain.
Wow, I'd just like to say I'd never heard of the word "marginalia" before, but I love it :)
Oh boy do I have a website for you!
I love browsing https://www.themarginalian.org whenever I have a few hours to kill. It's a bit like TVTropes, but much more "literary" for lack of a better word.
The author has spent decades building a digital commonplace book of everything she's ever read, and hyperlinked everything together in a way that you can get lost in her notes for hours on end and never surface. It's one of my favorite websites on the internet, and the best example of the power of marginalia and hypertext.
