The layout of the front page is quite flexible. Once in the theme settings, you can go to the "Block region builder" tab to modify the layout. This tab allows you to add 4 rows of blocks, and specify how many columns (between 1 and 4) for each row. Once you specify the rows and columns you want on the front page, you can save the page to view the layout. You can then go back to the front page and, while in editing mode, add various blocks in the rows and columns.
The image below shows the general layout of the front page.
