It won't be Fairphone. Fairphone is very far removed from the hardware requirements listed here https://grapheneos.org/faq#future-devices They don't seme to take security seriously at the moment, so the chance is low they are going to make the huge leap needed to meet the requirements. Fairphone heavily markets their sustainability but it's very relative. Fairphone doesn't give proper software support. They don't properly keep up with Android updates and also stop giving updates much more quickly than Google (8 years since Pixel 8) and iPhone. Giving proper software support is also part of what makes a device usable for a longer period of time and hence reduces the need to purchases a new device which has an environmental and climate impact. With regards to the hardware longetivity, Google has good repair programs for their Pixels. It's more difficult and less supported to do repairs yourself but it's certainly possible to repair your device.
