How can I store Coding Projects Locally but sync related documents to iCloud Drive?

I have many Git repositories I will need to keep on my computer, which after some research, I decided would stay only locally on the MacBook and not on iCloud Drive. The problem, then is that I want to sync documents related to these projects - including slideshows, text files, documents, spreadsheets, and images - that are not part of the Git repository but part of the projects - on iCloud Drive. My first thought is to use the .nosync for each of these, but the other problem is that iCloud is notoriously hard to navigate to, so ideally, my entire "Computing" folder is located at "~/Computing". My second thought is to store what I want synced on iCloud, then alias it to the ~/Computing folder, and this is what I am doing for now. But I would love a solution that I can set up once and never have to "maintain." How do I prevent the Git repositories from getting synced while syncing the others to iCloud?
