quickemu makes it pretty easy to launch macOS on kvm. I was able to launch it on my framework chromebook from the Linux terminal
Crostini and Android apps make it really versatile. I run the dev channel and there are all kinds of interesting features and experiments to play with. Arch instead of Debian for crostini.
Was really disappointed when framework discontinued it, but it seems like chromeos is converging into Android.
The flip side is that we now have crostini for Android. Chromeos android subsystem has not been updated to be able run it if you are wondering, heh.
