To be clear, almost every argument contains a fallacy in it. Having a fallacy in an argument only introduces the possibility of it being wrong, it doesn’t necessarily mean that it’s wrong.
An example of a valid argument is like:
P1: Socrates is a man
P2: All men are mortal
C: Socrates is mortal
The conclusion is guaranteed to be correct if the premises are correct. Most scientific arguments are technically invoking a fallacy or are invalid in some way, due to the extrapolation from an experiment in lab conditions to a more general conclusion.

You’re conflating two separate ideas.
A valid arguent needn’t any logical fallacy.
Edit: You’re talking about syllogisms? I think? But like that’s tangential to my point. See my new post addressing your other inaccuracies.
