How to familiarize myself with Azure?

Currently unemployed due to an illness. I'd like to use this time to upskill a bit.

I'm good with: Tableau, PowerBI, MySQL, statistics (descriptive, inferential)

Some experience with: Python (matplotlib, numpy, pandas)

​

In a lot of job postings Azure or Amazon AWS is listed as a necessary skill. How would you approach learning it? (The roles would be 'BI analyst' or 'data analyst' and adjacent fields)
