Taking a step back, it's worth understanding
why there's so much clickbait. Turns out that if the business model of a publication is selling ads, they're interested in reach. Generating reach is easier by having large quantities of shorter, and easier to produce stuff. This is true for videos, articles.
So if you're looking for more thoughtful things - which take time to produce - your options are:
1. Pay for publications that produce these. Ad-supported publications are unlikely to be able to budget for in-depth content. Just look at how eg BuzzFeed shut down their investigative reporting (which was unusually good). It just made no business sense to produce those articles when a meme piece or two would generate more ad revenue, while being 100x cheaper to produce.
In the tech world, publications that fall into the “paid and in-depth” category can be likes of The Information, IEEE, MIT Technology Review, and many newsletters, tech publications etc. Look for ones where ads is not their main business model.
2. Another source are people who do this for free... because they have a main job, and it's not a business for them to share their thoughts on things. These will typically be blogs, YouTube channels and other places. Based on your interests, you should be able to find plenty. Also, see this Hacker News thread about interesting blogs [1]. The only real downside is you won’t get these on a schedule, as it’s not a job for these folks.
3. Books and podcasts. Books are straightforward enough: they're meant to be deep, and reviews help do some justice on them. Podcasts are usually based on ad-based models, but most ads are less intrusive, and the format lends itself for thoughtful commentary. It's more time-consuming to listen to them over reading, of course.
I collect RSS feeds of both my paid publications, and thoughtful blogs using a reader (I use Feedly) and find this works pretty well.
