    The add bs=1m will probably work wonders for performance.

 The Natural philosopher says to clone both sda1 and sda2. I still wonder if sda1 should be cloned. It is listed as "firmware".

Yes. not only must it be cloned, because it contains instructions as to what patition the linux systren is in, but the linux partiton id must be cloned as wqell and that does not exost ionside the partibin, but on the raw disk
as well so that it has that partition number
That sounds to me

like it is on a flashmemory directly on the raspi5, and you modify it with raspi-config->Advanced options->Boot order.
 But I can try running both commands:
dd if=/dev/sda2 of=/dev/nvme0n1 bs=1m
dd if=/dev/sda1 of=/dev/nvme0n1 bs=1m
 

The second dd will wipe out the first. Dont waste my time, come back when you have demonstrated that it doesn't' work
I've been there and have the T-shirt
That's how I know what you have to do.
/boot in the older release is /boot/firmware in the new.
My Pi4Bookworn SSD that does boot has two partitionb on it
mounted on my desktop they show this
/dev/sdb1                                            510M   61M  450M 12% /media/leo/bootfs
/dev/sdb2                                            110G  5.7G   99G 6% /media/leo/rootfs
Bootfs is what gets mounted on /boot/firmware
rootfs is a traditional  Linux filesystem
In bootfs the cmdline.txt specifies
/media/leo/bootfs$ more cmdline.txt
console=serial0,115200 console=tty1 root=PARTUUID=778a9e44-02 rootfstype=ext4 fsck.repair=yes rootwait noswap=1
So that specifies the PARTUUID of the partition that *must* be mounted as root
That PARTUUIDs are shown a s follows
  eo@Juliet:/media/leo/bootfs$ sudo blkid /dev/sdb
/dev/sdb: PTUUID="778a9e44" PTTYPE="dos"
leo@Juliet:/media/leo/bootfs$ sudo blkid /dev/sdb1
/dev/sdb1: LABEL_FATBOOT="bootfs" LABEL="bootfs" UUID="5DF9-E225" TYPE="vfat" PARTUUID="778a9e44-01"
leo@Juliet:/media/leo/bootfs$ sudo blkid /dev/sdb2
/dev/sdb2: LABEL="rootfs" UUID="3b614a3f-4a65-4480-876a-8a998e01ac9b" TYPE="ext4" PARTUUID="778a9e44-02"
The partition IDs are not stored on the partitions, but in the partition table. This is why you have to clone the whole disk, to clone that partition table as well.
After booting linux will mount the original  bootfs on /boot/firmware (it used to be /boot pirior to bookworm) and the partuuid specified in cmdline.txt as the root partition
The bootfs will be re-mounted according to what is in fstab
/etc$ more fstab
proc            /proc           proc    defaults          0       0
PARTUUID=778a9e44-01  /boot/firmware  vfat    defaults          0       2
PARTUUID=778a9e44-02  /               ext4    defaults,noatime  0       1
All these ducks have to be lined up in a row or the bloody thing will not boot
