Many people claim that despite its popularity Godot has many drawbacks and performance issues. What is your opinion? Have you considered a framework instead of an engine? I'm a newbie dev myself and it's hard to find answers on this, thanks!
It's hard to find answers on this because it's an ignorant question. The question doesn't have an answer, because you're asking the wrong questions. Godot 4 doesn't have inherit performance issues. There are performance characteristics in the way that you approach a problem, just like with anything else. Inexperienced devs are always concerned about performance _before_ they dive into problem solving, but the answer is always to work through performance _after_ you solve the problem.
