We probably haven't met, but I think YAML is great. If you're doing a lot of work in python and ansible, then you just start using YAML everywhere.
I actually struggled with YAML at first when starting with Ansible because I didn't know it was YAML, and I didn't understand lists vs dictionaries in YAML (seems obvious in hindsight, but just didn't click for whatever reason).

YAML can be linted. Also, golang might be helpful to read i and deserialize your YAML files against a known-type so you can catch these type errors. This should probably be done during CI when you create a pull request or merge request. This obviously requires doing things on your end to make it all fit together.
