It does have a heavy focus on American writing and it's akin to a longform opinion piece, but I wouldn't let that get in the way of what makes for an accessible and pleasant read.
edit: What also helps is to sit down and write. Make a blog and even if you don't have a specific topic to focus on, just write and keep at it. Take a note of how you write, the style that you naturally develop with all of your quirks; do you overuse commas, do you routinely break up sentences with a dash or a semicolon? Does it have a sense of flow?
Before long something will click in your head, you'll become more cognisant of the world around you, and your head will be screaming at you to write certain thoughts and ideas down.
George Orwell's "Politics and the English Language" essay is a short essay that shares many of the pieces of advice [1]. The main principle that I've taken from both is that you will be more effective at getting your points across to the reader, if you optimize your writing for ease of comprehension, instead of attempting to sound sophisticated with unnecessarily fancy words. This is especially helpful in work environments, where getting your points across clearly can save yourself from delays due to confusion.
I would also strongly recommend reading good writing often. Becoming a regular reader of a well-written newspaper or magazine is great for learning new ways to write down observations or advance a point of argumentation, and I've also personally found it enjoyable to have a broader awareness of what's going on in the world.

If you like science reporting, The Atlantic has excellent reporters with this focus. The Scientific American and The New Scientist are also worth considering (along with the news and analysis-focused articles in the journals Nature and Science), though I've personally read The Atlantic more often as I'm also interested in the publication's articles about general topics outside of science reporting.
If you're interested in geopolitics, I highly recommend Foreign Affairs. The authors and contributors typically have interesting backgrounds in government or academia, and the essays are in-depth. Similarly to The New Yorker, the release of certain articles is itself newsworthy (often as senior policymakers of various countries are often guest writers)—as a direct result, the publication is closely read by senior policymakers of different countries. I also recommend The Diplomat as a comparable publication, with a specialized focus on news and analysis about geopolitics in East Asia.
If literary writing interests you, I would also recommend looking into some literary journals, such as The Paris Review, The Baffler, The Hedgehog Review, The Malahat Review, and Ploughshares.
These days, I personally listen to the audio versions of The New Yorker's Reporter At Large segments and The Atlantic's science reporting when I can. For the remaining publications, I typically download the ePub or PDF versions for reading on an e-reader (minus the publications that don't offer their issues in their format), and read just the articles that I find interesting on my commute.
For you personally, I would recommend identifying topics of interests that you are passionate about. You can then try to find high-quality publications about these subjects, which may or may not be on this list. If you're more interested in the focuses of the publications you read, you are more likely to develop a habit of reading well-written articles, which is helpful for improving your own ability to write.
In novel writing there's very old advice: plan to throw away your first million words. Actually, that's good advice generally, not just for fiction.

Writing is like hiking or skiing. While there are some important rules how not to kill yourself, you can only learn it by doing.
Also, read a lot, ESPECIALLY works by people who have a good command of your language (IDK if you are native English speaker; I am not). Writing style is a bit contagious. Don't worry if you occassionally sound like someone else, this kind of contagion is really unavoidable if you read a lot.
I would say that the optimal ratio of R:W time is about 5-6:1.

Hopefully this should help.
Do you have an idea what stands in the way of your ambitions?
Here are some suggestions (dang, I'm starting to sound like ChatGPT here):
1. Try an accountability partner and call them once a week to discuss progress.
2. Share your work, preferably to an audience you trust, and nourish feedback.
3. Experiment and train creativity. Write a short story, write with a pen, write technical documentation, write code.
Hope this helps.
You can't get better at writing without reading as much as you can, as widely as you can.
