There can be an option --interactive. So if you type "ls --interactive", you get a fuzzy search prompt, where you can enter free form text, which can be matched against the main page description of each option, and the options can be surfaces in a scored manner. This will be similar to the search bar under the help menu in macos, which is something I use a lot to find out location of options. Might work for a lot of apps.
