"Neural Networks and Deep Learning", by Michael Nielsen http://neuralnetworksanddeeplearning.com (full text)

The first chapter walks through a neural network that recognizes handwritten digits implemented in a little over 70 lines of Python and leaves you with a very satisfying basic understanding of how neural networks operate and how they are trained.

This is the thing that made NNs "click" for me, I think it was very good. Before this I did Andrew Ng's old ML course on coursera, so I thought that was a good intro to old ML approaches, common terms/techniques and flowed nicely into NNs.

But there's are both kinda old now, so there must be something newer that'll give you an equally good intro to transformers, etc.

+1 for this, when I was coming in as a complete newb to neural networks, this was the clearest and most accessible material I found.
