There are a few categories here, ranked in rough order of how much I want them between and within categories, assuming infinite storage space and the ability to read the format that it's in.
Knowledge/Entertainment: A huge subset of LibGen/Anna's Archive. Wikipedia. Survival guides. Tons of websites, especially smaller ones that might not get preserved. I think the NYTimes will be fine, but random indie websites, not so much. Lots of music. Project Gutenberg and swaths of the Online Books Page listed items. Videos, and of course VLC (if it's not already downloaded). Various coding things (I, I assume unusually for HN, am not a programmer and don't know any programming languages, might as well learn to code.) Minecraft or a knockoff, on the off chance I somehow get bored.
Creating: LibreOffice (if it's not already installed). If it works offline, the Inspiral app, because spirographs make everything better. Gimp, Inkscape, Krita.
Personal: Records of as much of my digital life as I can get. So comments, posts, etc. I want to be able to look back at who I was.
Organization: Calibre (again, assuming it's not installed). Obsidian.
