I would say that you should consume type of material you aim to produce. So if you are writing for news paper maybe follow a few and check historic examples deemed good. Same goes for blogs. And really academic publications are very much this.

I think reading short stories is a great way to develop both writing and storytelling skills. A SS compresses the storyline and character development into a more palatable and succinct morsel than can a full-sized book. And the brevity of SSs should make them more digestible.

Classic literature was written in an era when readers had more patience and fewer distractions than today. But classic short stories should offer the best of those, IMO, better-written times: more thoughtful exposition in fewer words.
