Should I use “ref” to pass a list variable by reference to a method?
Is the answer that “ref” is not needed (as the list would be a reference variable), however for ease in readability put the “ref” in?

No, don’t use a ref unless you want to change what list the variable is referencing. If you want to just access the list, do it without ref.
If you make a parameter ref, you are saying that the caller should expect that the parameter they pass in could be assigned to another object. If you aren’t doing that, then it’s not conveying the correct information. You should assume that all C# developers understand that an object reference is being passed in.
