Add text inside a shape in Numbers for iCloud
Select the shape, then type your text.
In the Format sidebar on the right, click an alignment button to align the text horizontally or vertically.
To change the font, size, color, and more, use the other controls in the sidebar.

You can also fill shapes with color, gradients, or images, or place an object inside a shape so it appears inline with the text.
