Hello
@Gudasau. Keep in mind that all of the new phone talk is only rumors at this point. Moto normally releases the G series in the Spring (G7 already released) and then the Z series in the Summer. So we don't know what the Z4 will be like, and if there even will be a Z4. I still think Shattershield is dead (too expensive, too many complaints, tech reviewers didn't understand it, etc) but hope I'm wrong.
Try the Files Go app by Google. It's a nice little File manager app that has a good Clean option and will show you all the files taking up space on your phone and help you clear them out.
