If Debian works on your hardware and you just want something that works and doesn't give you issues then yes its a good choice. It will just work happily in the background for years.
Fedora Server is a great choice if its something you want to continuously tinker with. Each release averages a little over 1 year of support so you'll want to do a dist upgrade after each new version comes out.
I'm currently considering switching to it on a couple of production servers I manage because they rely on PostGIS. EL9 and Debian rely on the official postgres repositories rather than shipping their own .deb/rpms and the official postgres repository's GIS packages are so unreliable I think it would be more stable on Arch. With Fedora server however I can just install postgres and postgis from the official community repo.
The SoC lacks the hardware. Even the USB C iPads with A series chips operate at 2.0 speeds. They can only do 5Gbit in host mode, like with an external SSD. Plugged in to a computer they are 2.0.
I would imagine future chips will have the capability, once the Pro chips trickle down to the base models.
