What is the best way to ensure a flow can be accessed by multiple pages within an app?

Using the utility bar is the best approach to ensure that a flow can be accessed by multiple pages within an app because the utility bar provides a persistent location for users to access tools and functionalities across various parts of the application. The utility bar is a component of the Lightning Experience user interface that remains visible regardless of the specific page being viewed. This allows users to easily access flows from anywhere within the app without needing to navigate away from their current context.

The utility bar can host multiple items including flows, giving it the advantage of centralizing functionalities in a way that enhances user experience and efficiency. By placing the flow in the utility bar, you ensure that it is always available to users, reducing the need for them to navigate back and forth between different sections of the app.

In contrast, options such as the App Launcher, Quick Actions, and Record Pages serve different purposes. The App Launcher is primarily a navigation tool that helps users find and open apps. Quick Actions are used for specific tasks related to a record, but they are not available universally across pages. Record Pages are designed to display information about specific records, which means a flow embedded there would not have the same level of accessibility across different parts of the app.
