First off, for this hardware, should I be using the aarch64 or armhfp images? I've been trying with aarch64 and that boots, but just wanted to doublecheck. Second, is it possible to get Gnome running? The "hardware status" wiki page says XFce is recommended, but it's not clear whether that means Gnome won't work, or if it's just not recommended. I tried the Workstation image and the firstboot wizard runs successfully, but then when attempting to login, gnome-shell crashes after chugging for a couple minutes and dumps me back at the gdm login screen. I tried adding 'cma=192M' to kernel args as suggested on the wiki, but no change.

If by reasonably well you mean that it runs a completely unaccellated
desktop rendered primarily on the CPU sure. The reason RPi4 is still
not officially supported on Fedora is because the accelerated graphics
isn't upstream, I've picked this up and are attempting to get the bits
upstream but time will tell there.

Basically all RPi devices are unobtainable ATM and I don't think here
is "go and buy more HW because the experience is less bad" is the
right response to this thread TBH.
