GrapheneOS is both, it is a privacy and security focused OS and would encourage reading of our documentation at grapheneos.org to dispel any myths.
As far as the other mentioned OS I have a previous note you can refer to here:

Is there a good FOSS keyboard? the one I have has weirds issues when using Amethyst when deleting words and whatnot.
Ya the native keyboard is terrible with Amethyst. I’ve had good luck with FlorisBoard
I use Florisboard for swype functionality okay, most AOSP based keyboards unfortunately have the issue.
