When to use the point form and when not?

Hi,

When should we list things in point form and when not? If I am making a list of advantages or disadvantages of a certain action to be taken, should it be in point form? I assume what is written in point form needs to be structually aligned, i.e. all starts with a verb or starts with a noun. One obvious case where we wouldn't normally write a list in point form would be a shopping list. I think what I am trying to ask is this: What should be the nature of a particular list for it to be in point form? A list made to make a point? I need more to understand this better. Thank you.
