How to effectively learn backend technologies?

Question

Backend

I made myself a list of things to learn.
It is not clear in what order and how to teach, that is, there will be no problems with theory, but with practice, it is not clear what projects to do.
List:
- PHP ( OOP, MVC )
- SOLID, DRY, KISS principles
- Doctrine ORM
- Docker
- REST API
- Laravel, Symfony
- MongoDB, PostgreSQL, NoSQL
- Git
- PHPUnit
- JavaScript -> Vue JS
I want to be a good backender , and not write sites on the CMS.
What resources are there to, together with practice, even for little money (by subscription type)
Thank you!

You need to understand that from a beginner (and even frankly speaking, from a pro), knowledge of all this is not required. Therefore, conditionally makes his news site on symfony + html + css + js + database. As it is completed, you can already go to get a job.
