I’m not sure if that make sense for me to answer that here, but I think you’re doing a great job at selecting tutorial, and I think blendernation is also very good to start a 3D journey. That’s a website I would recommend to students for instance.
It’s also great to get a daily dose of inspiring stuff, since I’m part of the 60% who don’t use social media 
The problem with tutorial, is IMO more with the community making tutorials. While there is a lot of information for beginners, and also a lot of quick tips that are useful to everyone, when you reach a
higher level you are much more on your own.
It’s difficult to find advanced knowledge , or learning material made by advanced users and even more on blender ( beside payed courses generally for other software ) There are some (blender cloud is great for that). But on the overall the information is a bit buried by entry level tutorials.
At some point to keep learning I need to look for knowledge elsewhere.
Here are a few channels I’m subscribing to on youtube :
https://www.youtube.com/@ArtOfSoulburn/videos : a lot of great tutorials about concept art, image composition, 3D…
https://www.youtube.com/@MatthewMerkovich : a 3D tracking guru, I don’t do 3D tracking a lot but I find his works super inspiring.
https://www.youtube.com/@FZDSCHOOL : a concept art god, I don’t draw much, but I learned a lot from these.
Sure all these are out of the scope of blendernation, and it’s up to blender community to come up with good material. But that’s the stuff I’m looking forward to a lot more now, and blendernation is getting less relevant for me.
hope that helps, thanks for taking the time to read !
