Since you mentioned Final Cut, I’m going to assume you’re using an iPhone. For music, there’s GarageBand from Apple. There are many third party apps too, many being free as well. For visuals, you have iMovie from Apple and many other painting/image/video/animation apps, also with many being free too.
