@ishfaq using Sharepoint is great.... azure is also fine due to the best option and collobartion that Sharepoint gives you, besides it also works with any platform and it is user friendly, recently it has been integrated with Microsoft Teams the Collobration and Communication platfrom from Microsoft.
The Security permission, Version history, and accessibilities and much more that comes with Sharepoint.
so looking at all the features I would suggest it is best to do it in Sharepoint.
