Associated Press https://www.ap.org/en-us/
Reuters https://www.reuters.com/
Both of these news sites have extremely accurate and mostly unbiased news. They are very trustworthy but not perfect.
Why are they so good? Both sell their news stories to hundreds of newspapers and TV news sites around the world. The more bias they remove, the easier it is to sell their stories.
And they have to protect their rep, it's valuable to them.
I don't find Fox or CNN all that trustworthy.
