I've read a handful, and agree that he truly understood the effects of technology and Modernity. It's worth reading the French sociologist/theologian Jacques Ellul, too (they were contemporaries).
I like Ellul unfortunately he is much more cloudy in his statements and analysis, it takes much more energy to decipher (even in French) and make your own what he's saying.
For Lewis Mumford [0] maybe "Myth of the Machine" - with his concept
of "megatechnics" - is more readable than the earlier "Technics and
Civilisation", but his earlier insights seem ever more relevant.
For Neil Postman [1] the standard reader is "Technopoly", but for me
"Amusing Ourselves to Death" is a real treat. It was literally a
description of social media and modern "performance politics" 40 years
too early.
I'd rather recommend reading basics stuff like Guy Debord (Society of Spectacle), André Gorz (Métamorphoses du travail), Schumacher (Small is Beautiful), Kohr (The Breakdown of Nations). A little bit of Bourdieu cannot hurt either
