If you want to go really in-depth I can recommend GTC on demand. It's Nvidia streaming platform with videos from past GTC conferences. Tony Scuderio had a couple of videos on there called GPU memory bootcamp that are among the best advanced GPU programming learning material out there.

100% this. You can find all kinds of detailed topics, like CUDA graphs, memory layout optimization, optimizing storage access, etc. https://www.nvidia.com/en-us/on-demand/. They have "playlists" for things like HPC or development tools that collect the most popular videos on those topics.
