Debian makes things a little harder than neccessary
Is that because unlike all "modern OS installers" since Win98 it doesn't give you a slideshow of how awesome it is and how you're in for a beautiful experience, while giving you little choice than the default set-up? :P
Seriously though: When was the last time you installed Debian? The graphical issues due to nvidia are gone, thanks to the nouveau project's development of a pretty good open source driver. But if you want proprietary blobs you just have to make sure you include "non-free" /and/ "non-free-firmware" in your sources.list. Then you can apt-install nvidia-driver, you can even apt-install steam.
Normally I get my installer images from https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/ but as the big banner says, firmware blobs will now be included in the standard debian installer images, so your WiFi will work for the installer. :)
