I haven’t been reading books, I’ve been primarily looking into these libs:
Docs: Introduction | Nez
Docs: Introduction | MonoGame.Extended
To see how they did things, have been making a scene-system, scene-transitions and scene-graph based on their techniques. Than I found the libs in the Discord, which is also very useful.
This guy makes short but useful videos about different topics in MG:
This guy makes fine videos on renderTarget (for multiple resolution support), physics, etc
This guy introduces you to shaders with a jitter-free pixel art shader
