You could check if some of the older tree roots yield a better result, as described in https://btrfs.wiki.kernel.org/index.php/Restore#Advanced_usage. In my case I had to go back 2 generations to get a suitable file list. I am not an expert though and am only recommending this as to my understanding, btrfs restore and btrfs-find-root are non-destructive to the original file system.
