I have been involved in many teams where we used PlantUML for sequence diagrams, which are specially helpful to explain a complex process.

To me, I have saw considerable performance improvements when sharing sequence diagrams to devs that are not very familiar with a project or its domain.

Unfortunately, sometimes it is complicated to understand when a diagram is worth it because while an experienced dev can find something obvious, an less experienced one can struggle on that for a while.

EDIT: I forgot mentioning that these diagrams were super helpful when presenting solutions to technical customers/partners, instead of preparing a PoC, we could just create the diagrams to explain the proposal flows.
