Picking a new system to try

Hi! Big time ttrpg fan here, but the group I play with and I have only ever tried DND 5e, and would love to break out. I’m writing a short 3-session max arc for us to play through that is a comedy-horror. The purpose is for us to try to branch out for the first time, and I’ve been looking at rules light, roleplay heavy systems. Any recommendations?
