What’s the best pawn structure for a beginner to learn first?

i already posted on this but i want to elaborate because this seems like a hot topic and i have a hot take, a beginner will not understand pawn structures and learning it is a waste of time, just like learning opening theory as a beginner, none of it will be understood and is like jumping into a whirlpool before learning how to swim, the best thing to learn as a beginner is the actual reasons that you should be making moves, example, to have a pawn structure.
if you push a pawn to the 4th or 5th rank as white, you can decided to move another pawn forward to defend it... if moving a pawn doesn't immediately hang a piece and defends another pawn (or is defended by another pawn), you have just created a pawn structure.
i do not know anything about pawn structures or opening theory and i am 1250 in rapid, most beginners are around 300-500
