Yes, to address to criticisms of your comments and siblings, in my experience if you start changing fonts, then you need to change margins and paragraph spacing, and down the rabbit hole you go. The thing is, a small change is not very complicated, but the defaults are also really good. So if you just want to get below a certain page limit, then it is easy to change the margin. If you start to wanting to improve the overall look of the document, then it is usually a much better idea to play with different packages were someone else already did the hard work instead of trying to improve details by yourself.
