Didn't use LVM?  Too bad: that means there's a risk your new dirve and
partitions will get new identifiers so your fstab may need to be adjusted.

macOS doesn't touch EFI, AFAIK, so don't expect the Time Machine to
touch it either.

This sounds rather complicated.
Here's what I'd do:

1- take out the old SSD and put it into an external reader that you can
   connect via USB
2- put the new SSD in
3- connect the old SSD via USB and boot to its macOS this way (if you
   can boot into Debian this way, even better).
4- create the same partitions on the new drive as you had on the old drive.
5- Use `dd` to copy the content of each partition from the old drive to
   the new drive.
6- reboot without the old drive.  You should be done.
