I have had great success with the following (as far as quiet boot goes, I haven't tried any splash screens yet)

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty3 loglevel=0 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait logo.nologo quiet splash

I will keep it without markdown so its more easily read. For me this works and only displays a grey box with the three dot loading screen then goes straight to the login prompt.

If you want tty3 to login automatically:

sudo raspi-config

Select Boot Options, Select Desktop/CLI , Select Console AutoLogin

sudo cp /etc/systemd/system/getty.target.wants/getty@tty{1,3}.service
sudo nano /etc/systemd/system/getty.target.wants/[email protected]

Then on the last line edit DefaultInstance=tty1 to DefaultInstance=tty3
