Hey team - getting a new system and seriously thinking of disk encryption. Is the instruction in this link pointing in the right direction?

I don’t know how far GRUB is with the LUKS2 compatibility but the lack of it was the primary cause to add an extra partition to hold boot as this avoided the long decryption time when using GRUB.
If you have no intention of dualbooting - I recommend doing a manual install and use systemd-boot as bootloader.
There is a couple of guides on the subject either here or in the archive just search for it.
