Lapham’s Quarterly: https://www.laphamsquarterly.org

Depending what kind of thing you're interested in: Harper's, The Economist, Vanity Fair.

I recently discovered the Congressional Digest at my local library, seems really good so far. https://en.m.wikipedia.org/wiki/Congressional_Digest

The Sun Magazine is still an ad-free pleasure.

I really like reading 2600. Some articles get kinda... biased, but I think they do a decent job of striking a balance.

It's nice reading about tech-related things that aren't just blockchain or Facebook. The particularly fun ones are just little side projects someone writes about for a few paragraphs/pages. No real major point or grand purpose. Just a neat thing they did.

The Economist.

I still subscribe to Science News. It's mostly smaller digests with one long-form article per issue (it's bi-weekly and thin) but it is a genuinely enjoyable read, and gives you lots of jump-off points on subjects you didn't even know you were interested in.
