Why would someone choose Ubuntu instead of Debian, or Nobara instead of Fedora? Unless a derivative offers a clearly specialized goal—such as CachyOS focusing on speed and responsiveness—it seems like choosing the original distribution would be simpler. What practical benefits do derivatives provide, and when are their preconfigured changes worth using instead of setting up the upstream distro yourself?

Derivatives are usually customized starting points. They may enable different repositories, include drivers and codecs, change default software, provide a particular desktop configuration, or apply optimizations for gaming, older hardware, security work, or ease of use. You could often recreate the same setup on the upstream distribution, but the derivative saves time and reduces friction.
The tradeoff is maintenance and support. Larger upstream distributions tend to have bigger communities, more documentation, and a better chance of long-term maintenance. Smaller derivatives can be more convenient, but you are relying on their maintainers to keep their packages and custom changes working. If you do not need the derivative's special defaults, choosing the better-supported upstream distribution is often the safer option.
It is also about defaults and philosophy. Ubuntu makes choices such as using GNOME, Snap packages, particular fonts, and its own tools and update policies. Debian has different priorities, generally emphasizing stability and conservative package versions. Neither is universally better—the useful choice depends on whether you like those decisions and whether they match your needs.
Some derivatives target very specific use cases. A security-focused system might include a large collection of tools in its repositories, while a lightweight Debian-based system may carefully select software for old hardware. A distribution designed for a Windows-like desktop, a travel USB, or newer hardware can provide a tested configuration that would otherwise require a lot of manual work.
The main difference is the out-of-the-box experience. Nobara, for example, adds gaming-related packages, repositories, fixes, and configuration on top of Fedora. A gaming-focused derivative can let you start playing immediately, while configuring plain Fedora yourself might take hours. People who enjoy building their system from scratch may prefer the upstream distro; people who want a ready-to-use system may prefer the derivative.
That makes sense—the documentation and support advantage is easy to overlook when comparing only the default features.
