I've had a great experience with two paid resources: CGCookie.com and blendermarket.com. CGCookie is a monthly subscription site that has courses on modeling, materials, sculpting, and a lot more. They just refreshed their course on mesh modeling for Blender 2.8x [1].

Blender Market can be hit or miss since it is user-created content that varies from really amateur to quite professional. If you want to learn the ins and outs of shaders in Blender, I highly recommend these two courses from the user "Blender Insight" [2][3]

I think Youtube tutorials are the way to go.

Blender Guru is the most popular channel, but I personally prefer the tutorial series[0] by Grant Abbitt for getting started.

I just went through Blender Guru's donut tutorial and it is excellent as it covers a whole progression from learning the basic UI to modeling, sculpting, texturing, shading and even a touch of animation.

For a change of pace, look at Ian Hubert's "lazy tutorials". Each one is only one minute long but simultaneously shows something amazing while making it seem like anybody could just pick up the tool and do it.

YouTube tutorials. There are many of them. It's great to follow along at first since they'll teach you about the UI.

I did the CGBoost beginner series last summer. It's a paid course but because if that it's much more comprehensive and higher quality than a lot of the free stuff on YouTube.

It takes you from zero to making an animation of a sci fi car traveling through a desert.
