At the start of 2020, the Switch only offers these two themes. You're basically just deciding if you want a dark theme or a light theme. However, both the Nintendo 3DS and Wii U eventually gained support for purchasing and downloading themes, so the Switch will likely also get the feature in the future.
Will the Switch ever get themes?
You can choose between a basic white, and a basic black theme in the System Settings. As of right now, Nintendo does not offer additional themes for purchase or download for the Nintendo Switch. This is a feature that will likely be added at a later date.
