As for Rafinha, even if he scores 200 goals, Barcelona will continue to promote Yamal (at least because some of the assists will be on him). Barcelona threw Rafinha into a hole even in the 24-25 season, when he was very good, in favor of Yamal and this will happen again. If Yamal gets injured, then the second choice will be Rodri, Rafinha has no chance of winning any PR award while he plays in Barcelona. Rafinha NO for me is literally like a bank deposit - low profitability but high reliability.
But what do you mean by "Barcelona will continue to promote Yamal"? The winner(s) is chosen by journalists, and they are supposed to know quite a lot about football, so if Rafinha performs better than Yamal what could Barcelona do about it?
Of course Yamal is and will be Barcelona's face for the next 20 years (or at least that's the idea) since he comes from the cantera, he's Spanish, he's young, etc etc. Raphinha is "just" a foreign player arrived from Leeds who is almost 30 years old, we're not talking about a Messi situation. And I don't want to belittle what Raphinha has been doing because he's incredible at the moment.
