You need to understand that who pays for playing, always also orders the music. Hence he deadly enemy of the propaganda is the independent journalism.
A state-funded media will mostly publish that the state officials want to see. It may still avoid lying too often because the reputation suffers. A company website may publish lots of nonsense about they product that may not be even safe to use. A website of a political party will skew all facts to support the goals of the party.
But if business of the company is to acquire and sell the truth for money, they will go long ways to ensure this truth is good enough to sell. If you buy the truth from them, you are they real customer. You pay for the playing. You are ordering the music.
Journals like The New York Times and The Guardian send they own correspondents to war sites. Reuters employs around 2,500 journalists and 600 photojournalists in about 200 locations worldwide. Somewhat every few days a journalist is killed in Ukraine. Some of these independent journals have more than hundred years of history in producing and selling the truth, for money. This where the trust comes from. Новая газета got its license revoked while not even publishing anything at the time, almost getting funny.
Independent journals do publish information the reader does not particularly enjoy reading but anyway wants to to know. When it turned up that Germany is extremely dependent on Russian gas, when Ukraine lost Sievierodonetsk and was actually unable to stand against Russian artillery, when 100+ Ukrainian soldiers have been killed daily, when Viktor Orbán defended Patriarch Kirill, when decision has been made to extradite Julian Assange to USA - the independent journals have written about this. In August 29, 2021, USA used bad intelligence information to conduct an airstrike that killed civilians and no any terrorist. The army initially denied this happening. They only acknowledged the truth after the independent press wrote about this.
Buy the truth from independent journalism. Buy the truth for money, the truth is worth it. Do not "just google", look not only what has been said but also by whom. Remember, free cheese is typically found in a mousetrap. And (inferring from your username), no, you do not need to rely on western sources. Support Russian independent journalism, some now closed journals now attempt to reopen outside the Russian boundaries.
Extend the concept of "foreign agent" by making no exceptions to Russia state. Entirely state funded media outlet is equally and possibly more not trustworthy.
