Learning resources (exemplary projects) for an intermediate javascript dev

I am a web dev beginner, looking for the next steps to increase the quality and style of the code I write.

My experience consists of creating internal company websites in HTML/CSS-Bootstrap-Material/javascript-D3-Angular. I learnt a lot making those sites but realised i needed to improve my style and convention. I read Uncle Bobs Clean Code book to improve this - and i am now producing websites with those principles in mind.

I feel like my next steps are to learn more web technologies/frameworks and deepen knowledge of some of those I have used already; but i feel like its fairly easy to learn things like angular - without knowing how to properly apply them and structure/manage the code effectively. I also have the issue that I havent seen much of other peoples code (its usually other part time DEVs who need to get better at the basics), and so havent experienced other approaches and ideas used to produce a web solution.

I dont have the opportunity to view or work on any exemplary code in the office; these are mainly my own projects.

Are there any training resources or stores of exemplary javascript projects that you can recommend to help me write better structured code and learn quality approaches to common web solutions?

Or a different way to get this experience? Should i just get an entry job as a web dev (currently a DBA, 24yo).
