Backup options for Sierra MacBook

Hi all. I am planning to upgrade from Mojave to Sierra and want to get some file backup tips. I am tiding up my Macbook and currently categorising things that are important for me. What backup should I use to keep my files in case I need them after the update? I’ll do TM backup but I am also thinking about SuperDuper Backup as well? Also, should I clean up drive through Onyx for Sierra before the upgrade?
