 It's not Windows, you don't need 3rd party tools to do simple things such as copying files to new discs, everything you need is provided, although it may not be obvious what to do.
 Option 3 is the best, as both the drives can be connected to the Pi, booting from an OS image the SD card allows you to perform the copy.
 As long as your new NVME is larger than the SSD, you can just do low level copy with the dd command, then resize the rootfs partition on the new drive to use any extra space with the gparted program (if not installed use: apt install gparted).
 e.g. dd if=/dev/sda of=/dev/nvme0n1 bs=1M status=progress
 Use fdisk -l to find the nvme disk name as it may not be as above.

Thank you very much to all for taking your time to reply.
By now I think the first solution from druck will be my first try (when I get the NVME). I have before been looking at creating an image (as suggested by Chris Townley today) , but ran in to things I did not understand, or was ment for an earlier version of raspberry pi os. Then i posted the question here.
So if we look at the df -h listing from my first post:
raspberrypi@raspberrypi:~ $ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            3.8G     0  3.8G   0% /dev
tmpfs           805M  6.2M  799M   1% /run
/dev/mmcblk0p2   57G  5.0G   49G  10% /
tmpfs           4.0G  368K  4.0G   1% /dev/shm
tmpfs           5.0M   48K  5.0M   1% /run/lock
/dev/mmcblk0p1  510M   75M  436M  15% /boot/firmware
tmpfs           805M  160K  805M   1% /run/user/1000
/dev/sda2       234G   19G  203G   9% /media/raspberrypi/rootfs
/dev/sda1       511M   76M  436M  15% /media/raspberrypi/bootfs
Then the system to copy is on the 2 last lines. Correct?
And following drucks first suggestion I should run these 2 commands:
1: dd if=/dev/sda2 of=/dev/nvme0n1 bs=1M status=progress
and
2: dd if=/dev/sda1 of=/dev/nvme0n1 bs=1M status=progress
replacing the name of the NVME to what I see when it is installed on the raspi.
Best regards, and thank you for the help.
