MediatrR is useful for CQRS or if you structure your app around event dispatching. I use it some time, but now I will spend a day or two writing a library because I don't need anything fancy.
Automapper is not a concern. With AI you can map a class to another very fast and have better performance.
For MassTransit I don't care. I work with microservices since at least 5 years and we either used RabbitMQ, NATS, Kafka, Azure Service Bus directly or write our own wrapper.
