Driving a 7 segment display
I have a few of these, but was wondering if there is a way to run one, or a series of these, without using 6 GPIO each.

I found this, but has anyone found a ready-made module for numbers?

You mean like this: https://www.adafruit.com/products/879
i2c controller would do it with 2 gpio and would be easy to code, And this is ready made.

Use a shift register! The 74HC595 is perfect for this.
Instead of arduino use vocore GPIOs
