I have a similiar problem. I can´t say that I´m overwhelmed per se, but I tend to switch a lot between the things I want to learn, because I want to learn everything ar once! Ok, might be ” being overwhelmed” as well :´D
I would stick to the “Introduction to Blender” learning flow. It covers all the basics you need!
Afterwards, take a look at the “Modelling in Blender” learning flow and watch all the “Modeling I” courses, since they cover some more fundamentals. It get´s a bit tricky after. You might think “Hey, why should I want to learn how to create a wall of mailboxes or a jellyfish?”, but even if the main subjects of those courses don´t interest you much, the instructors introduce a lot of techniques or mention useful tips and solutions during said courses. Maybe start with the courses that interest you more, but try to complete the whole flow, since you can learn something new in every video.
I hope I was able to help you a bit 🙂
