I setup Fedora Silverblue for my son a few years back for his first computer (he was 7). It worked well for his simple needs and was very low overhead in terms of management for the obvious reasons. An immutable OS may be overkill but it was also a bit of an experiment for me to see how well it worked as a desktop given the restrictions and limitations at the time. It is a bit smoother now as progress is made with flatpaks etc
