I can comment a bit on your second point.
There is a work in progress for FP2 support. I have created a binary test version in August, see /e/ OS “easy” installer: development thread about adding new devices
Not sure if anybody but me has tried it out, though.Whoever tries it should be prepared to potentially switch over to the manual flashing method. But at least the installer will bring the necessary tools to do so.
There’s also some hints how to diagnose in case something doesn’t work as expected: Howto troubleshoot issues with the easy-installer
