"Instead to meet e4 I'm looking into The French Defence and the Karo Kann. Both interest me and seem far simpler and easier to get a fundamental grasp of."
++ French and Caro-Kann are objectively weaker and thus more complicated to play than the Sicilian. Simplest, strongest, and easiest is 1...e5.
I'm sorry, what?

World champion Lasker wrote what is common sense: "Common Sense in Chess"
It is completely according to his own practice. As white he played the exchange variation of the Ruy Lopez, to punish the tempo loss 3...a6 moving another pawn than the d- and e-pawn. As black he avoided 3...a6 and played the Berlin. It is even consistent with the practice of modern grandmasters. Look at the Ruy Lopez games of the recent Carlsen-Nepo World Championship match. In what games did they play other pawns than d- and e-pawns in the opening phase and on what move?
You can disregard as you want, but do not tell people that common sense is 'oddity' or 'nonsense'.
