As for C, the "suitable" subset really depends what we expect from a browser. In my experience, I was forced to use a Chrome based browser only for work, because mostly for google web apps (Google Cloud and Google Meet come to mind). For browsing the small web, I'm sure smaller browsers can work well. I tried some, but was usually put off because of the lack of adblockers, and I also quickly miss the element picker zapper feature of the ublock origin extension.
