Hi Justin,
As Phillippe already stated... what is your goal?
What do you mean by "everything to a hybrid env."?
For example, first, you have to differentiate between M365 and Azure. M365 is more the application part, and Azure is more of the data center part.
If you want to move your CRM application into the cloud... it mostly consists of - at least - an application server and a database server... it doesn't make sense to move the application server into the cloud, so you have to move both servers...
The easiest way is to deploy two virtual machines and migrate the application and its data. Maybe you decide to move to a database as a service like Azure SQL MI.
But your main question was - how do we start?
Simple as that - find a person in your company that will take/have the responsibility and "power" to make decisions. That one has to provide a company mail address and a credit card. Then create a new account in Azure.

Or, if you want to... start with the Azure free account...
Read and practice the tutorials in the Microsoft docs, or use the tutorials in the learning paths.
For example, this one from the AZ-104 exam, "deploy a virtual machine"...

(You'll need an Azure account to run the tutorial in a free sandbox environment)
I hope my answer is helpful to you,
Your
