Depending on your shooting style, either lens could serve as a versatile tool.

Portability and Design
Portability is a significant consideration, especially for photographers who travel frequently. The Canon EF 50mm f/1.8 STM Lens is compact and lightweight, making it easy to pack for various shooting sessions. However, the RF28mm F2.8 STM Lens takes portability to another level with its pancake design, making it one of the most lightweight lenses available for full-frame cameras.
