I'm a DDD convert, but boy do I still have trouble selling it. "why do we need a ubiquitous language?" "why can't I jam everything into a single domain?" "why can't everything be an aggregate root?" "It's too complicated, why can't I just PATCH my data directly into the database from API?" Honestly for me it's these abstract principles and practices that outweigh any flavour of the month technology. DDD encourages code to model the business domain, meaning the complexity should equal that of the business. A lot of problems I see with apps are due to reducing complex domains into CRUD ops, then trying to build the complexity on top as an afterthought.
