If your data was encrypted with FileVault as is typical, then the password is the key to decrypting your data. And a robust password means no access to the data without the password. Any bad sectors are also encrypted.
As for erasure, SSDs do not work at all like hard disks with erasure and overwrite, either. SSD storage sectors are automatically erased when the contents are deleted, and there is no direct means to overwrite contents, nor are multiple-pass overwrites (as was recommended back in the floppy disk era) useful.
Follow the previously-linked Apple documentation.
