Disk Drill seems to be a popular app from a good developer (they've been around for over a decade IIRC). I've never personally used it though.
Hopefully a Quick Scan will be sufficient to recover your sessions, because if a lower level deep scan needs to be performed, then you will be shown a huge number of items without any file/folder names. It is nearly impossible to make sense of the overwhelming amount of items if a low level scan is needed.
You should make sure to have frequent & regular backups of your external media (including the cloud) just like you should be doing with the data on the internal SSD of your Mac computer. With proper backups you should not need to worry about a data recovery app. Besides, it is becoming more & more difficult to recover data from even external drives and it is nearly impossible to recover data from an internal SSD of the recent Macs due to all of the hardware, software, and security changes.
