I like golang, but nearly all of the learning resources seem to assume that the reader already has a lot of prerequisite knowledge about programming. There are a few exceptions, none of which I found to be easy to follow. But learning programming isn’t easy no matter what, so maybe that’s not a big deal.
These two are my favorite balance of fundamentals and getting to purposeful application as quickly as possible (the first link is definitely not enough, but combined with the second she should be comfortable with the syntax and able to get basic things working):

This one takes its time with fundamentals and includes some projects to put them in context of building something. It’s presented on Google Colab and Jupyter notebooks: https://allendowney.github.io/ThinkPython/
Working with GIS data means cleaning data. This one covers that and a lot of common analysis tools and techniques. But it assumes a bit of programming knowledge (Good to follow up after one of the options above): https://wesmckinney.com/book/
