Some alternatives to one on one feedback (learning to write):
1. Read a ridiculous number of books in different genres.
2. Goodreads 1 star reviews of popular books. They're a goldmine of what not to do, which influences better methodology and attention to detail.
3. Youtube film critique and analysis channels. Most of what happens on screen translates perfectly to books, especially mechanics like pacing and transitions. At some fundamental level, stories are stories. Even discussions of camera lenses and cinematography can better shape our prose.
4. Watch lots of televisions shows, both episodic stuff and long format serials. Game of Thrones was a masterclass on how to do it right, which was mind-numbingly contrasted by Season 8 and how to do it all wrong.
5. Same for movies. Watch them over and over with an eye for structure and mechanics, especially the powerful scenes and how and why they work.
6. Read poetry and song lyrics, study the cadence with the music so you can get a sense of how rhythm works in prose. Sentence structure can be a very powerful tool in building emotion in the reader.
7. Immerse yourself into the writing world 24/7. Make it your life - not a hobby or a job. Hobbies are too hit or miss, and with a job, you go home after work.
Real WritersTM are never truly off the clock. Find people you can discuss story with, that means books and film. Read about it, listen to Ted Talks, whatever. Be a sponge. You're developing your literary toolbox.
8. The point of all of this IS NOT to make a checklist. By writing regularly, and applying what you're learning, you'll get to a point that you just kind of know how to use the tools you've developed.
9. The journey of discovery, that is - our search for tools never ends. With every story we get better, we learn new tricks. I could not have written any of my books without having first written the one that came before it. I've improved whatever chops I have with every outing. I do believe it's important to write kind of a lot if you want to get good at it, though, just like a musician must practice their instrument.
10. We're going to fail along the way, and that's okay. Learn and do better next time. Hemingway said, "We are all apprentices in a craft where no one ever becomes a master." That's why we need that objective reader.

With all of that said, I still think that new writers should work with a developmental editor a few times early on. It comes down to not knowing what you don't know. A good editor, who understands what you're trying to do (this is essential), will advance and hone your abilities and voice faster than any other method. It's like working with a great coach, they tell you what's working and where you need more practice.
But as I said upthread, at some point, you know how stories work. The down side to all of this is every new show, film or book is probably going to become way more predictable. It's the downside of knowing how the sausage is made.
eta: Have patience. This is going to take a while.
