> JSON, which is [...] unambiguous about its types

With the one exception that with floatig point values the precision is not specified in the JSON spec and thus is implementation defined[1] which may lead to its own issues and corner cases. It for sure is better than YAML's 'NO' problem, but depending on your needs JSON may have issues as well

Also JSON's complete lack of many commonly used types, and no way to define any new ones.

Isn't that a problem with most of these config languages, though? XML is the only one where I think this might be possible.

Allowing you to define types is quite uncommon, but many config languages allow more types than JSON (so more than boolean, number, string, list, dict). Date datatypes are a big one and are provided by about every second JSON variant, in addition to TOML, ION and others.
