That is going to be way more dependent on the encoder used than ffmpeg itself. x265 uses WPP AND frame-threads by default if you have multiple cores, and I doubt ffmpeg would disable that. Turning off WPP silently would be a big problem, as WPP also has significant decoder impact as well, particularly with multithreaded software decode.

It's an ongoing challenge with all encoder to make sure that the right flags are allowed by products that incorporate them. Making sure that commonly used tools like ffmpeg integrate libaom (or a superior alternative) well is pretty darn important, as that's what lots of reviewers and evaluators will use.

Getting good, actionable documentation into ffmpeg and in general is also important. Listing options without explaining why one might want to use it and its pros/cons isn't really documentation. x265.readthedocs.io is the gold standard here, and I don't even have a runner up.
