> Permissions in GCP seem like a mess, I’m trying to use python to get credentials and there is a whole python library for authentication and getting credentials (google-auth).

I feel you, but I gotta agree with the other commenters that it's really just about time and experience. Anyone long-experienced on one public cloud will really struggle switching clouds. Your experience is low but your expectations are high. You're not just poking into a dashboard trying to spin up a single VM, you want to do all the stuff you're used to doing on AWS.

While IAM does feel easy once you know it, as someone who's run hackathons and bootcamps I can say it's not easy for everyone to just pick up. It's as complicated as it needs to be, but yeah it can be a steep learning curve.
