OP I think you have an issue I see in the FIFA generation more and more and it undermines all the points you are trying to make. First of all, talking about Son being a Left winger or an inside forward- just call him a Left sided attacking player (apart from this season) whose role varies depending on tactical need.
Next, when talking about attacking impact look at the wider picture and the impact the player has on those around him. Kane and Son hold the record for the most goal/assist combinations on the PL so he must have been doing something right.
A good example to underline this point is Jack Grealish for Man City, his numbers on paper are poor but he has a clearly defined role in the team to draw defending players to him and allow his team mates to exploit the space this creates. Does he grab the headlines?- no. Does he contribute to build up play? Of course.
