A few minor nits, and one optional suggestion on using the VerticalStepper component for sequential steps. Otherwise looks great.

@amychen1776 - to address your questions about adding this to the sidebar, it's autogenerated in sidebars.js:

        {
          type: 'category',
          label: 'Data lake',
          collapsed: true,
          collapsible: true,
          link: { type: 'doc', id: 'use-cases/data_lake/index' },
          items: [
            {
              type: 'autogenerated',
              dirName: 'use-cases/data_lake',
            },
          ],
        },
