Best ways to improve as a beginner?


Dont focus on openings, instead focus on principles like what you said, develop your knight to protect your center, try not to block your bishops in, protect your king i.e. castle early. Eventually youll notice reoccurring themes like when a knight and bishop team up on f3 of f7 vie ng5 or ng4 etc. (then play h3 or h6) study pawn breaks when you feel like youve got the basics down and study basic endgames which you will need to know to be able to convert middle games. If you are comfortable with endgames you can try to build your middlegame skills.
