Hi Rob!
Thank you so much for this script, it worked well for the specific document. I ended up playing around with ChatGPT and through many trials and errors I created a script that allows you to specify a font, style and size to apply a paragraph style throughout an entire document. I have 0 scripting experience so I can't say this code is as clean and simple as it should be, but it is exactly what I was looking for and I figured I should share it!

var paragraphStyleListbox = dlg.add('listbox', [0, 0, 200, 200], getAllParagraphStyles(doc));
paragraphStyleListbox.selection = 0; // Default to the first style
