CORE is a superb choice to start your journey into Blender. Once you’ve done the basics series it’s a perfect choice. It will give you a very good introduction and fundamental knowledge in every aspect there is in Blender (except geo-nodes) and once you have that basis you should be able to pick your battles after that. You’ll learn the tools on a deeper base than in any free resource out there. And if you can get it on sale right now, that’s a great deal.
With that you’ll get more out of free resources afterwards, in my opinion, because you’ll understand why things are done, not just see that they are done, which is the case in most (not all) YT tutorials for example. Plus the community here and on the discord is always there to help.
