It may be unpopular but speaking from experience, I think using boilerplates can lead to slower rate of iteration.

A lot of these boilerplate project make strong opinionated decisions which can be in conflict with how you build and structure your project. Meaning whenever you need to make modifications, you'd need to fully go through how it is done and could be counter intuitive to modify.

Also, for starting a SaaS, the initial version is probably better to be as simple as possible rather than a bunch of advanced features. Which means you'd be starting to slash features from the boilerplate at some point.
