Advices for interior animation scenes

[spoonyboy]

Hello,

I have several interior animation scenes to render but they are not optimized regarding lights and also materials. The goal is to have a good render in 720p for all animations and a good ratio quality/rendering time.
Could you give me some advices and tips about lights (lights to use, settings) and also about materials and general scene settings which can improve the optimization ?
You can find my scenes here : https://drive.google.com/drive/folders/1ElH3DqEhWi802uMp_RWCipKp7m_jVQde?usp=sharingand any feedbacks would be great !
Thanks.
