By now we should all question basically everything, especially if we can’t easily verify it ourselves.

The problem with that is there is virtually nothing in life you can verify independently, outside your own little tiny sphere. You would drive yourself insane!
You can externalize trust within certain boundaries.
Give alternative voices a certain trust budget, consider their theories critically, remain open to extend/change your world view accordingly as new information turns up.
For example, when its about health, you can't just experiment on yourself just because someone claimed their concoction fixes all disease because if you fall for a scam, you just fucked your body up. But you can analyze the presented theory, check if it's at least internally consistent, if the presenter is open to scrutiny, debate and criticism and measure their responses. If they don't push products and seem genuinely independent, how they behaved in the past, all that.
Sure, this takes time and dedication. But if the alternatives are different stages of ignorance ("clown world, who cares" or "trust the science/authorities") I'd give it a try.
It seems you are talking about checking things thoroughly and agreeing or not. You certainly cannot verify everything.
You aren't sitting in a lab breaking down and doing trials on the different compounds and elements I mean. Well, I doubt it at least. 😂
You should see my alchemy lab in the basement! 😂
