I'd also like more comprehensive write-ups on such topics but either I haven't found the right sources yet or all the people who know how to set up and keep modern fabrication infrastructure going are too busy raking in the cash and making stuff. ^^

If you like visual media, the "Strange Parts" YouTube channel is an interesting source for glimpses into modern, mostly Chinese factories: https://www.youtube.com/@StrangeParts/

Since you're asking about pick and place specifically, https://www.opulo.io/ is an interesting example of how far/cheap you can push such machinery (and the design in and of itself is interesting from a manufacturing point of view). Not all that relevant from a mass-production point of view, though.
