Add Category to display on a theme Page


I’m hoping someone can help me. We all know category pages can look a bit plain. I’m looking to add category listings to a theme page. This way, I can have a more visually pleasing page that truly matches the rest of the pages.

I found a plugin in Plugin Directory (Add Category to Pages). It’s exactly what I’ve been looking for, but it haven’t been updated in two years and it’s creating a conflict. Does anybody have a solution?

Thanks in advance for your help.
