I had to re learn how to land after being taught the "arrest sink rate at 50ft" and then getting sick and tired of nearly missing the TDZ every time. Best advice? FCTM. It says start flare at 30ft then cut the throttles. Every landing is different: wind conditions, weight, aircraft variant, engine variant and even flap 3 or full. But that technique is a good starting point to get the feel of the plane and then fine tuning it to the specific scenario. As other said, the retard call is a reminder, cut the thrust as you see fit, doing it at the wrong time makes for some bottom clenchy moments. Bonus tip: leave the thrust that extra bit when landing in conf 3, one extra second of thrust helps a lot.
I've also recently discovered the "bank 1.78 degrees to the upwind side" cheat and it works wonders for when you want to show off! Lol But stick to the "mathematical landing" for now. The proper feeling will come with time
