if you have network access, I would suggest to take the net version as it is
minimal and you will get all the latest packages from the network during
installation, so consequently you do not need any large usb.

you can dd the netinstall to the usb it should work

What you are thinking will not work unless you modify the partition table,
so that it may see the rest of the disk - when you do dd it will write only
the image and the rest of the drive will be not usable

I usually mount the usb and do debootstrap installation, or when you finish
the installation, you can just copy your installation to the stick and make
it bootable.

No Win10 will not be happy with 120GB - better take 300GB from the large
disk for windows and the rest for data linux, windows or both

might be better, but remember you have to enable it in bios before booting
the netinstall

fdisk is not suitable for GPT

gdisk - GPT fdisk text-mode partitioning tool
parted - disk partition manipulator

Basically read the debian documentation and then try to implement.

Also previously it was advised to install windows first and debian after,
but I do not know how Win10 is behaving in the context of UEFI, as far as I
understand it, the order should not matter for GPT
