The Best Practice to set page permission for different users can be done like below:

• Create a new role if required else use the existing roles
• Set organization permission for the role
• Identify the pages to permit for the role and create/modify the new/existing Menu with selected pages
• Assign the menu to the role
• Assign the required roles to the users
• If required set functional permission for the pages (incase required to set No access to a page which is the menu OR to set Full access to a page which is not a direct menu page)
• Login with that user and make sure only the mapped menu related pages are listed for the login user
