How to make sure none of my deleted files on my Macbook SSD are recoverable?

I want to sell a somewhat older MacBook (2019) that I have, but I want to make sure none of the deleted files are recoverable. This mac book uses an SSD with trim enabled. Not sure if simply deleting the file and emptying the trash can is enough. What else should I do to prevent any chance of deleted files being recovered?

How to securely delete files from an early 2013, Intel based, MacBook Pro with SSD Have older MacBook pro's (early 2013, Intel, macOS Catalina, 10.15) I want to prepare to be recycled and I want to erase the files to a reasonably secure level... Harder to do with a Solid State Driver, right??? What's the best thing to do to prepare such computers for recycling??? Included as an option would be to open up the computer and remove to mechanically destroy the SSD... Is that doable??? Easy to locate compared to what is battery??? Need help to get more than one computer ready to be recycled... Help would be much appreciated... thanks...

Slow external SSD Bought a Crucial 1TB SSD along with a caddy to use as a back up drive for my files on my iMac. First few Gigabytes was really fast in transferring but then it started to get slower and slower to the point where the speed was like a traditional HDD. I know about enabling TRIM support from my older mac a few years ago. Could my problem with the slow SSD be related to no TRIM support?

Within a few seconds after you empty the Trash on an SSD drive with TRIM enabled, the blocks containing your data are clumped together into superblocks, bulk-erased, and their block numbers are deleted.

Your data are gone.
