Yeah I think the recent nonfree images should take care of the most pressing driver issues (last time I installed Debian, I had to separately download and put on a second USB stick the drivers for my WiFi card just to be able to proceed with the installer). I don’t know if you still need to manually install proprietary blobs for the CPU or the GPU post-install tho. If not, that would mean modern Debian is indeed very close to OOTB functionality.
