commonplace, ordinary, employment
庸 centers on the idea of being unremarkable and serviceable: something ordinary or commonplace, and by extension, the kind of steady, unexceptional work that keeps daily life running.
庸 is thought to combine 广 (building) with a component related to use or service, suggesting something employed within a structure. The exact historical development is uncertain.
Under a roof 广, the inner part looks like a hand holding a tool 用, doing ordinary, everyday work. That's 庸: commonplace employment.
For ヨウ, imagine a yo-yo used in an ordinary, everyday job: yo-yo -> ヨウ, and the worker spins it under the roof.
