As “another pro tip”, use an area2d to check if the player is colliding (around) with interactive objects; So instead of doing labels for each fruit you just do one general “cast” and that’s enough to verify if the player can interact.
Myself I create stuff like this just for this kind of casting. It can be attached from a simple “billboard” and up to NPCs. Try studying a bit of polymorphism and “ECS”, which both will give you enough route to expand, build and debug a lot of your future projects (And this one also if you want to keep adding stuff to it).
That was my 2¢ but overall the actual pro tip is: Games are a farce/illusion, just focus on making pretty farces/illusions and that will do for most games (shaders and baking textures/lights exist for a reason…)
