To me it's like Jota thinks about football from the defending team's perspective - how he can make it as hard for them as possible.
First, he takes his finishes very quickly, before any defender has time to interfere. That requires skill of course, but mostly the right mindset and intuition. This makes him hard to defend, even though he's not particularily quick or strong
Second, he finishes on goal and usually low. He puts the ball where it's the hardest for the goalie to reach.
He would rather take a quick but not super powerful shot, than take an extra touch to set up himself for a perfect shot.
Compare with Gravenberch's goal: He takes two touches before the shot and everyone can see that he will shoot. That means that he needs a basically perfect shot to score - which he did. I dont mean to criticize Graven for that, he took advantage of the space, but in the box you seldom will have that kind of time and space.
