Hope that helps!
We are small compared to FAANG, but not "small" small (~4000 employees total).
We run our own self-hosted GitLab EE instance, so we have "infinite" CI minutes in that the runners are on all our own hardware. So CI is "free" (but we pay for and maintain our own hardware/VMs so I'm not sure how much that costs).
Might be useful for you depending on how long your builds take. I haven't personally used it but I it's one of the things on my todo list for next month.
Getting that to work with GitHub is more painful (pain mostly related to automated webhook-management)
I can't compare to GitLab right now ;-)
For CI/CD I quite like Appveyor and Octopus Deploy. But if you are penny pinching, they may not be super appealing, but they are incredibly powerful!
My company switched to BitBucket in order to pinch pennies, and now I weep when I have to get Jenkins and BitBucket to play nice with each other or to do something. GitLab CI just works, is easily horizontally scalable without paying exorbitant prices for more "agents", etc... I miss GitLab...
