Optical media costs more per GB/TB than hard disks. It’s lower capacity and slower so there’s more hassle swapping discs. One time use media generates trash when the data on the disc is obsolete. Discs are a better fit when the use case calls for read only access or physical copies cheap enough to literally hand out. Such as ransomware resistance or evidence chain of custody. For offline copies you could just be diligent in unplugging external hard drives and testing backups.
