I think it would be a great experience for you. If you are super worried you could try on a used device or be open to switch back, as both iPhones and Pixels ahve decent reselling value.
You sound like you are not relying on the Apple ecosystem, so you shouldnt lose out as much as others with lots of other Apple devices/services.
Also GrapheneOS has been the best Android experience I had, because it taught me not tl rely on Google services, embracing FOSS alternatives and actually caring about hoe my phone works / what data my apps can access.
