SAP checks most of the boxes of almost all industries you need to run a modern business. Some specifc domains better than others, sure, but none are actually bad or unusable. And all tjose functions are integrated with each other. That alone is tremendous value.
Some weaknesses I see with SAP compared to dedicated solutions are in logistics and warehouse management, process industries (e.g. continious chemicals production, SAP is way better for discrete products and still it works just fine for the pricess industry), aerospace MRO (SAPs aerospace and defence package is more geared towards production) and eCommerce (eCommerce as a business is not that complex).
Basically, if you are a manufacturing company SAP is easily among the best solutions out there. Added benefit of using an ERP that litterally everone else is usong as well: you have a way larger pool of people to recruit from that know the system. The less market pebetration an ERP has, the harder it is to get people who prwviously worked with it. That means higher training efforts, more need for external cobsultants and performance issues until your emoloyees adapted to whatever ERP you have.
