My news-savy neighbour's strategy was to combine several sources, Channel 4[0], Al Jazeera, <can't remember> and sheepishly, RT (this was mid-2000's). He rationalised the last one as not being a reliable source, but as a way of seeing what others weren't covering. Al Jazeera is great for anything outside Qatar's interest and their early days included actually talking to real Israelis which was something not seen in most of the Middle East at that time.
It's much better if you can get an outside perspective. The right wing papers in the UK were selling Brexit as the sunlit uplands. The leading right wing paper in Canada, the Globe & Mail, called Brexit the height of stupidity. Judge for yourself which sources were better.
Double down on external sources with that second language that you've been meaning to learn. Lazy propaganda doesn't cross language barriers very well, so it stands out - almost as much as promoted content in English on a non-English Reddit sub. (but first, learn the words for "wounded" and "killed" as they are in half the headlines)
Sources change, too. The BBC used to strive for impartiality. Now, their national news spouts the government line, but the regional news hasn't got the memo and regularly runs critical pieces. I think the World Service is still it's own unit.
