How to securely delete files from an early 2013, Intel based, MacBook Pro with SSD

Follow these instructions: What to do before you sell, give away, trade in, or recycle your Mac - Apple Support

Flash memory such as may have been originally installed in your Mac or in a solid state drive does not require nor does it benefit from a multi-pass a/k/a "secure" erase procedure that may have been applicable to magnetic media (and even then its effectiveness was debatable).

You can physically remove and destroy the storage device if you wish but it's not necessary. FileVault makes its data completely irretrievable and worthless without its encryption key — which itself becomes irretrievably and permanently destroyed upon erasure: Encrypt Mac data with FileVault - Apple Support

You originally asked about recycling that Mac, not someone else's future use of it.

Either way Apple's selling / trade in / recycling instructions are more than sufficient. FileVault renders data utterly irretrievable to anyone without its password. Erasing it eliminates even that possibility, while retaining some future owner's ability to repurpose that Mac as his or her own.

Filevault's purpose is to encrypt the data so once the decryption key has been destroyed by erasing the drive, the encrypted data is no longer accessible. With an SSD (at least ones with TRIM enabled like an original Apple OEM SSD), then even a simple erase with Disk Utility will destroy all data on the SSD due to how SSDs work. Once the SSD blocks have been declared to be un-needed by macOS, the TRIM feature will reset those SSD blocks to zero or an indeterminate state. I have personally verified this occurs by using a macOS command line utility to look at the raw data on the SSD.
