I have been looking at CalyxOS as well. All three make a great eco-system. We do LineageOS for the wide phone support but we know how to port it to other phones. Now to find a good backup app for non techies is my next challenge. Thanks for saying hello.
Also consider CalyxOS - the most secure. I do consider GrapheneOS to me more private and easy to install!
