Send to a lab, that's the only way to recover the files. If photos are irreplaceable make sure the card is taken out of the reader, it should not get power. You can not recover this using file recovery software. Many Sonya camera's send the SD Card equivalent of an ATA TRIM command when you format the card.

Raw or JPG? I just tried to replicate this on my a74 and no files were found by Recuva So, again, perhaps something new with A7M4 or maybe a new version of Recuva has some kind of SD card secret sauce not previously tried. Up until now I have never heard of anyone successfully recovering files after a Sony in-camera format. Other cameras, like Canon, give you a choice to do normal or low level format, while Sony would default to low level. Traditionally, all Sony cameras did a low level format by default rather than just deleting the file table. Its possible something changed in the A7M4. That said, I have not had any success in recovering the video files I was hoping to recover. Perhaps the new A7M4 no longer low-level formats. All photo files recovered, so I am not sure why others are experiencing issues with their formatted Sony cards. I accidentally formatted (in camera) before copying over the video files. I had great success with a Sony A7M4 SD card and Windows Recuva - free version (running in Parallels on an Intel Mac).
