Seems you're missing my personal favorite, extensible data notation - EDN (https://github.com/edn-format/edn). Probably I'm a bit biased coming from Clojure as it's widely used there but haven't really found a format that comes close to EDN when it comes to succinctness and features.
Some of the neat features: Custom literals / tagged elements that can have their support added for them on runtime/compile time (dates can be represented, parsed and turned into proper dates in your language). Also being able to namespace data inside of it makes things a bit easier to manage without having to result to nesting or other hacks. Very human friendly, plus machine friendly.
Biggest drawback so far seems to be performance of parsing, although I'm not sure if that's actually about the format itself, or about the small adoption of the format and therefore not many parsers focusing on speed has been written.
