Scheduled Task to check for updates

I am going to be creating a scheduled task to check for any file updates to a folder in box.  The folder is not owned by me, but I have been given access to it.  I'm using .NET to create the app to login as me (to see the folder), and retrieve the items inside.  (I would use Box Sync, but it does not work inside Scheduled Task or Windows Service on a server).

My question is which type of box app should I choose?  I'm assuming Partner Integration or Enterprise Integration.  I only need to login as myself. 

I'll be building a console application, so cannot use Standard OAuth 2.0 since I do not have a Redirect URI.  Assuming OAuth2 with JWT is the way to go, however the comparison chart on this page (https://developer.box.com/docs/authentication-types-and-security#section-advanced-features) asks Where is Content Stored?  For OAuth2 with JWT it is not stored in the user's Box Account.  

Or, is it possible to create a Custom App using App Token(only uses primary/secondary token to login), and share out a folder to other users?
