I completely agree with everything you said, except:

> Cloud specific services and persistent storage will be the main issues, but that's something you can't really get around.

That isn't wrong necessarily, but products like OpenShift Container Storage (OpenShift Data Foundations now actually) can provide a common API to erase that problem. ODF uses Ceph under the hood so you can get block, file, and (s3 compatible) object storage no matter where you are.

Cloud specific services are indeed a problem, but many of them have open source/portable solutions that you an choose that can run everywhere. Such as Fission, RabbitMQ, Kafka (not my favorite), Argo CD, etc. Really the things I run into most now are things like AWS machine learning services.
