Great summary. I recommend uMatrix (https://github.com/gorhill/uMatrix) which has really good controls for toggling not just JavaScript but also cookies, XHR, frames, etc for origin and 3rd party/cross-domain requests with per-site settings. A lot of websites that need JavaScript will still work if you enable loading of scripts from the origin domain but leave things like Google Analytics, etc, from other domains blocked. uMatrix is also easier to use and has a much smaller footprint than ad blockers.
