I like the idea of creating a OSS project, and then build extra on top of it for selling.

The OSS part ensured that even if I went full Sam Altman, the user will still have an absolute baseline they can fallback on. And given how lazy I am, the OSS is often basically 70% of the project. This also has the benefit that the significant part of the code can be audited for security/etc, sometimes even for free.
