You should specifically use argon2id. Please ensure this, because some older LUKS2 setups defaulted to the weaker argon2i. This post by Matthew Garret contains information about that:

NOTE: You should also read the instructions about about GRUB_TERMINAL.
Rebooting system in case of freeze
Linux kernel has a feature to do actions to the system any time, even with it freezes, this is called a Magic SysRq keys. You can do these actions with Alt + Sysrq + Command. These are the actions:
- Alt + SysRq + B: Reboot the system
- Alt + SysRq + I: Send SIGKILL to every process except PID 1
- Alt + SysRq + O: Shut off the system
If some of them don't work, you have to enable it in the kernel
command line paramter. So append sysrq_always_enabled=1 to your
GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub
You can also run # sysctl kernel.sysrq=1 to enable them.
Fedora won't boot?
This may also apply to CentOS or Redhat. Chroot guide can be found on fedora website
linux16 issue
Libreboot's default GRUB config sources fedora's grub config
grub.cfg (in /boot/grub2/grub.cfg), fedora by default makes use of the
linux16 command, where it should be saying linux
Do this in fedora:
Open /etc/grub.d/10_linux
Set the sixteenbit variable to an empty string, then run:
grub2-mkconfig -o /boot/grub2/grub.cfg
BLS issue
With newer versions of fedora,
scripts from grub package default to generating BLS
instead of grub.cfg. To change that behaviour add following line
to /etc/default/grub (or modify existing one if it already exists):
GRUB_ENABLE_BLSCFG=false
Then generate grub.cfg with:
grub2-mkconfig -o /boot/grub2/grub.cfg
