Give Andrej Tarkovski's filmography a try if you love fast-paced cinema.
Also check out Stray Dogs (2013).
A guy stares at a wall in silence for, like, 15 minutes.

Genuinely beautiful movie though.
I think plenty of pre-70's movies are very easy to follow and fast paced.
Especially when they are under 90 minutes, they need to get to the point quick.
Like a Bergman movie is dialogue wall to wall and it's usually quite short (by modern, obnoxious, 150min movie standards).
Some have this idea that you just watch those older movies out of filling up the cultural landmark quota, but something like Day of Wrath is genuinely amazing to watch today.
The interrogation of the old woman is not gut wrenching "for the time", it's gut wrenching. Period.
Cinema is a more mature artform than something like videogames, so its technical evolution, it's not as much of a barrier to the artistic merits and depths you can find in older works.
Similar to what happens with literature (though to a lesser degree, because cinema is still beholden to a technical framework), you wouldn't think twice about not reading a book from 30, 50, 100 years ago, because it's "outdated".
Either way, unless you're genuinely diagnosed with ADHD (and then there's medication), i think the idea of low attention spam is a form of habit.
I love slow burns, but when i consume a bunch of junk entertainment for a while, i can feel my attention span decreasing, until i "clean" up and ease back into it again.
This is true for more complex videogames, harder to listen music, etc etc.
