I think Fedora Media Writer kind of hits those boxes, and the Fedora installation (with the Blivet partitioner) is fairly easy.
My problem, however, and Brodie on YouTube can attest to this, is the language. Open source projects have a problem with communication, messaging and signalling.
It should be the priority of design and the UX to properly communicate actions, events, consequences, etc. It’s also about accessibility, as bad messaging can be confusing and off-putting.
