Working with the keyboard to move resize, focus and arrange your applications is a great productivity tip. When I changed from Windows to macOS a few years ago, I had a pretty convoluted setup based on Slate for managing keyboard shortcuts, especially for moving applications around, but this has since been simplified by using Spectacle instead of Slate.
Spectacle has everything I need, especially keyboard shortcuts for maximising an application, of “flinging” it over to another display.
Spectacle is free and comes highly recommended, give it a try!
