If it’s more complicated than that you 100% need a progressional to do it for you, even if that means calling fidelity/etc and having them take a look.
I don't particularly like the news, but it pays the follow certain types of news that could have an outsize impact on you.
Furthermore, the "prescribed" ultra long equities/diversified index fund allocation strategy you alluded to above is relatively new by historical standards. It's possible that this strategy doesn't pan out well in certain types of prolonged global economic states (such as persistent global stagflation, as one example).
I'd agree with the above if your investment strategy had been around for longer (more "Lindy"). One example folks like to cite is the Talmud Asset Allocation:
“Let every man divide his money into three parts, and invest a third in land, a third in business and a third let him keep by him in reserve.” -Talmud

One example of a portfolio that might be more robust is one of 1/3 land, 1/3 personal business/equities, 1/3 emergency fund cash/gold/bonds. With that portfolio, in just about every time period in human history, you'd probably be okay and wouldn't have to worry about the news at all.
Maybe there is something better! I, along with your average uninterested person, won’t be the ones to find out.
Cash holds a lot of risk. Inflation destroys savings.
