It seems that mounting Shared Folders in VMWare Fusion with Debian 10 is not as the docs say. This is the way I got it working:
sudo /usr/bin/vmhgfs-fuse .host:/src /mnt/src/ -o subtype=vmhgfs-fuse,allow_other -o uid=1000 -o gid=1000
Where the uid and gid fields match my Linux uid and gid so that permissions are correct on both sides of the mount.
This will work even if you do not have fuse installed but if you try to add it to your fstab it will fail without fuse.
For people who can't stop tooting!
