Hello & welcome to Linux! To be honest, I haven't found a good reason to zero any media, unless I was decommissioning it and/or selling it. When you create a new file system on installation, any new information will overwrite the old one. And as soon as it's created, the old file system won't be able to interfere with the system anymore. Besides, with SSDs and some newer HDDs, you can't be sure that there won't be something left over in a block that was marked defect and isn't accessed anymore.
