The programming model and the operational tasks are also quite different across serverless and microservices. Microservices are by now an old and well known way to develop software (and even there transactions and orchestration aren't easy). Serverless could force you to break down application logic very differently and slow your coding. Which serverless platform and language are you considering? What's the tooling like? What the Developer Experience like? Operational workload should be less in theory with serverless. But that only holds if your software scales smoothly. Or else you'll have more complexity to deal with than microservices.
