One thing I've appreciated is summaries. Means the newsletter author is actually putting some thought into what they include, instead of just copy/pasting some links.

Another approach is custom content: write stuff yourself. That gives you a more personal connection to audience, helps you learn by teaching, and tends to suffer less from trendiness of link-based articles. This is what I do with https://codewithoutrules.com/softwareclown/.
