    In elementary school my son would not memorize addition and multiplication and just use strategies like this.

    That became a problem later on as we just can handle a finite number of intermediary results in our brain, so just memorizing the tables reduces a lot of mental load for calculation in your brain.

    Another thing that helped him a lot was just writing down intermediaries on a piece of paper.

    Btw it was a bit similar for me, I just got the table memorized perfectly and got faster doing simple calculations in my mind than using a calculator when I was training the multiplication and addition tables with my son.
