What form did Byzantine artists use most frequently and was commonly used in the home?

The form that Byzantine artists used most frequently and was commonly used in the home was the icon.

Icons were religious images, typically painted on wood panels, that depicted Christ, the Virgin Mary, saints, or other biblical figures. They served as a focus for prayer and meditation, and were often placed in homes, churches, and public spaces.

While other forms of art existed in the Byzantine world, like mosaics and frescoes, icons were particularly popular due to their accessibility and their ability to connect people with the divine.
