Connect to SharePoint online from .net console application and Azure functions

Question

We have 2 SharePoint online tenants which have ApplOnlyPermission disabled, and we need to do the following for creating a scheduled jobs which connect to SharePoint online:-

1) On the first tenant, we want to develop a .net console application which runs on Windows server 2016 on-premises and scheduled using windows task scheduler.

2) On the second tenant, we want to develop an Azure scheduled function.

At this stage i need to list what are the licenses and subscription we need to have. And based on my reading on these 2 links Granting access via Azure AD App-Only & App only authentication in SharePoint Online using latest Azure sdk, i listed those :-

1) Subscription for Azure App Registration
2) Subscription to key valult to store the certificate
3) Generate a self-signed certificate
4) For azure function we need a subscription to it (which i think will be per usage).

Question one) Is my list correct and complete? or i am missing something.

Second question, now i know that using self-signed certificates should only be used for testing purposes and should never used in live systems, but on the above 2 links they are using self signed certificates, so is this fine to use self signed certificates on live applications in our case?

Thanks
