The ones made by Nikolay Naydenov. Lots of courses, with different characters and styles. Some are simple, some are advanced, etc. Watched the "Dragon Girl" and "Full game character in Blender". I was noob to mid level at the time and it helped me a lot. Just checked and they are with a huge discount, like, 5USD in local currency. I think it's worth it, but I'll check it later to see if it holds up.
"Anatomy And Form In Blender", by YanSculpts, also. Watched later, after getting a tablet, and it was pretty good. It about anatomy, but more in depth, obvious. If you plan on stylized characters, then this one is kinda overkill.

"3D Cars: inside and out", by CG Masters. Kinda advanced, but if you can model a car using hard surface techniques, then you can model anything. And the dude explains everything super well.
Never heard of this one you mentioned. It looks very good and cute. Probably a good start. Besides that, honestly, it's practice. Hard surface is very straightfoward. Just don't depend on plugins and shit, actually learn topology and try to finish smaller projects first after going into something complex.
DECODEDVFX and Mario Elementza, on YouTube, are very good. The latter uses Maya, but most 3D softwares share the same principles, you only need to know which buttons to press to achieve the same result.
If you're a beginner, then I suggest following a basic YouTube tutorial you like. Anyone that teaches you what buttons to press is enough, just don't waste too much time. After that, try to actually do stuff, like, finish projects, even if they are small, maybe following a more advanced tutorial, etc. Keep in mind that different areas require different things. Game dev will require X, while animation production requires Y, etc. This is more in general since I don't know what you want.
