MacOS has a frustrating tendency to depend on external utilities for basic functions, but I've found Maccy to be as good as if not better than Windows clipboard manager. You can summon it with a keybinding or click on an icon in the menubar. It's really good and one of the first things I install on Mac.
Facebook does (or at least used to when I left it a few years ago) this too. They give you a huge dump of your data and photos, with an html file to help you navigate it better.
To offer a differing experience, I've been working in Angular for a couple of years now and personally like it quite a bit. I don't like frontend frameworks in general, but given the choice I prefer Angular over React.
Bob and Brad ("the two most famous physical therapists on the internet") are an absolute treasure. Always good to see them get some appreciation online.
