I, for one, would love a monthly email newsletter that summarizes the top ~100 news stories of the past 30 days. Things that turned out to be irrelevant would be ignored, while things that turned out to be important would be included and briefly commented upon.
Magazines like The Economist sort of fulfill this role, but they are often a little too detailed for the high-level overview I'm looking for.
The Economist does include a one page summary of the week's news near the start, with just one or two sentences for each story. You can use that to decide which you wish to read a whole article about later in the paper. You can even choose not to read any, though admittedly it would be a bit expensive to buy the paper and read only one page of it. (There is also a page about business news, reflecting the publication's title, and it's often worth looking at the first couple of those.)
Also worth looking at unconditionally are the letters page, which is always very good and sometimes has very famous correspondents (occasionally from tyrannical regimes making preposterous statements, with no response from the paper), and the obituary, which has an eclectic selection of very famous and very unknown individuals.
I think of something similar but less "news" lead - for example a backlog of the most "important" global issues (yes we can out climate change at number one) but it's things like "water shortages in southern sudan" at number 18 and so on that really will give perspective - when we see things like Brexit at number 67 that we know we have a proper balance.
I would start with a metric like "estimated number of excess human deaths from this issue in next year, five years fifty years" and have open transparent ways to assess the metric
