Not sure if there's an english website about it, but in Portuguese quality content you can find without paywall I would say is NeoFeed https://neofeed.com.br/

Brazil Journal too, but it usually focus more on market as a whole. https://braziljournal.com/

But most of the news are usually covered on Infomoney, Valor Economico, with the together with daily market coverage.

NeoFeed and Brazil Journal focus more on "high-quality", less content.
