I tried that for a month, but most sites I encountered on search engines will just break or even refuse to render unless I enable JS. At first, I tried to leave the site and find an alternative, but after a while I found myself enabling JS on every site I visit that requires it, which negates the whole point.

You should check out uMatrix to get even more fine grained control over sites.

I usually allow images on every page, that's it. Some need CSS, some need iframes, and a small subset of websites I visit are actual webapps that need javascript.

I love uMatrix but development on it has stopped so it won't receive bug fixes and it will probably stop working someday. I don't think I would recommend new users start using it.

Yes true, but it's still working mostly and I don't have a real alternative.

I want to switch to uBlock's Advanced mode which seems to do similar things, but I haven't yet.

The UI is much less clear on what is blocked or not compared to uMatrix. I definitely prefer the latter.
