Ball size is regulated by the RoG, so the ball frontal area is essentially a constant.
Based on my experiences I agree with the OP's assessment, at least as a basic rule of thumb. One has to look closely at the wind direction indicator, and no doubt, a lower ball trajectory decreases the effect of the wind.
In a 10 mph 90° cross wind, at 100 yards the ball will be blown 10 feet left or right of the aiming point.
So a 75 yard wedge shot will move left or right 7.5 feet , and a 300 yard tee shot will move 30 feet left or right.
For wind angles on a diagonal, I find using 75% of the wind speed for a 45° angle more accurate than 50%.
Then you need to figure out a way to accurately determine where left or right of the point you want the ball to land that you aim for by moving the aiming point or by using the early/late ding method.
I often use the aiming point box. From many of the alternate views in front of and behind the green, I have found the width of the box to be about equal to 10 feet.
Some of those view are from further away from the green, and I adjust my assumption of how wide the aiming box represents accordingly.
I multiply the wind speed by the shot distance after adding a hundredths decimal point to the distance.
If I have a 90°, 13 mile an hour wind and a shot distance of 182 yards, I multiply 13 x 1.82 = 23.66 feet that the ball will be blown sideways.
If I have a 90°, 13 mile an hour wind and a shot distance of 67 yards, I multiply 13 x .67 = 8.71 feet that the ball will be blown sideways.
