Surprised you didn't mention "analyzing games I played to find viable alternatives or understand opponent blunders." The greatest improvements to my score came from reviewing every game and using the "Computer Analysis" feature on Lichess to see other, stronger moves. This helped a lot in breaking out of old patterns and not making the same mistakes twice. There is a famous series of chess textbooks they use to teach kids in Russia, and two of the important "commandments of chess" if you will, are: be able to visualize the board (seems crazy to me, still) and review/learn from your games.
