Azure Cloud Shell Now Supports Exchange Online

Everywhere I see articles on Cloud Shell I can't find anyone who tells you what the bare minimum Azure Storage subscription you should spin up if this is all you're going to use in it. Someone here said it should cost less than $1USD/month but when you go to the Azure calculator there are so many options how do you know what to pick? Bryan Hall above gives some closer guidelines, just don't know what "Type" of storage to pick, what capacity (GB) to start with, and how many storage transactions to estimate.

If I choose Block Blob Storage, Standard tier, General Purpose V1 type, 1GB capacity, 100 transactions, it's $0.06USD/month which is great. Would this be sufficient for a few PowerShell commands/month, for example, with nowhere the need of 1GB storage? I don't know if the Linux VM takes more than 1GB or if that's just included... lots to figure out here.
