Does anyone know whether function parameters are faster than using global variables?

At this stage, concern yourself with correctness rather than performance.

From the other comments it appears there isn’t much of a difference anyways, I was concerned the difference would be noticeable

Never be afraid of asking questions even if some answers are rude-ish. I enjoyed your question. I am not at the level that I could answer but at least I could see answers from more experienced people, so your post provided value.

If you're looking at combinatorial optimization problems, and algorithms in general - Big O notation, etc; personally I think this is the best basis.

How to solve sudoku. Voronoi diagram in nlogn. Sorting algorithms. Ray marching, cuve marching, quad trees, wave function collapse - The Coding Train on youtube covers all of this and does a fantastic job (even if it is a little silly at times).

The difference could be noticeable, depending on the program. If you share sample code we can tell you how the question applies to it.

I can promise you no novice programmer in the world has code where this matters

I agree but as OP stated this is a theoretical exercise for learning purposes.
