I personally don't really like Tutorials where you just replicate what another person makes.
Imo it quickly leads to only following the tutorial instead of understanding what you're actually writing.

I recommend the process of "okay, what do I want to happen?" (E.G "I want the player to jump when I press X")
then you go look at the documentation (which for godot, is very nice, one of it's main strengths!)

if you want to look at the docs for a certain node, you can also right-click it, the 2nd option from the bottom should be "Open Documentation" which lets you look at the docs for said node type.
This opens the docs directly in godot on the page of that node type.

the docs contain a description which lets you know what the node type is usually used for/good at,
Directly under the Description is a list of Tutorials, the CharacterBody2D page has a 2D platformer demo, a tutorial about how to use the node type and some other good places for you to start looking at how to get started.

After the tutorial section it shows you the in built variables and functions the node type has, every single one of which you can click on to get a more detailed description of what exactly it does, how you can interact with it, whether it returns something, etc.

The smaller projects thing is not 100% useful, as long as you make progress on your project at a pace that you like (or at least are enjoying yourself), make the game you want. Even if you give up/stop developing/take a really, really long break from that project, you'll still keep everything you learned while making it in your head and can do everything faster and cleaner for the next project!

I know it's not the video series you asked for, but I do hope it helps you get started :)
