You can install here a desktop/login manager - gdm3, lightdm etc OR just use xinit without an GUI interface

Xwayland works with gdm3 and gnome only for now.
Xfce4 works with lightdm and xorg/x11.

sudo dpkg-reconfigure gdm3
sudo dpkg-reconfigure lightdm

To start video mode:
systemctl start lightdm 

sudo apt install wget
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
dpkg -i google.....deb

sudo apt -f install  --- to fix dependencies error from above

Go to directory /usr/share/kbd/consolefonts - and ls to see all available fonts

then setfont iso01-12x22.psfu.gz 
or any other fonts you like from there
