Everything in financial markets is highly nuanced. So first thing to say is don't look for simple answers. Also remember that when narratives become highly census that's typically when the risk of the majority being off-side is the highest.
For example, a claim like: "US trade with China is in decline" could be for various factors – is that because of lockdowns, China's slowing economy, geopolitical relations? Etc... You also have to ask geopolitical questions here. If China's trade is structurally declining with the US might they take actions to restore that trading relationship? If they don't what might the consequences be? And could these consequences be reasonably accepted by China's leadership or may their hand be forced to take action regardless of their current opinion?
CNBC can be useful, but is not a good place to form opinions because almost everyone on there has bias. CEOs have their stock price to pump. CIOs have their funds to pump. Economists often have some political or economic spin they're looking to push. Economics also isn't reported on great by the media. If you read an economics article on say CNN or the Guardian you'll typically get something that's very dumbed down and misses all the important nuance. It may also be biased. I find FT and Reuters are slightly better, but you still need to be careful.
My advice would be to simply disconnect from financial media either literally or mentally. Admittedly I often watch CNBC but I just consider it entertainment, I don't actually weight anything that is said there.
Instead I tend to look at official data. Sites like Fred (https://fred.stlouisfed.org/), BLS (https://www.bls.gov/), SEC (https://www.sec.gov/edgar/search/), etc.. You just need to Google around, you'll find reliable data for most things you're interested in.
Then when you have the data start asking questions... So as an example I know I'm thinking a lot about public debt at the moment. I'm trying to understand what level rates would need to get to before major economies begin to struggle with servicing their debt, what the consequences of this would be, and what could cause that to occur? Could rates in the UK hit say 8% if nat gas, oil prices and food commodities jump in price again over the next year? What would happen to the housing market if this happened? Could the government service their debt if rates remained high? Would taxes need to increase to service that debt compounding the economic pain? In such an event might inflation just be accepted as the only solution? Then importantly, how should I position my finances given risks I see?
I find I have lots of weird opinions on economics for this reason which I can back up fairly well. I'm often wrong, but I also often see things before others. It's fun too.
It takes a very long time to learn this stuff to any competency though... Most things in economics tend to be complicated, interconnected and counterintuitive. I still feel like I understand nothing.
Learn the basics first you don't know that though... If you don't understand and can't account for business cycles for example most questions you ask will be meaningless.
