> AWS Lambdas, for example, is constant maintenance hell for larger applications, including building and dependency issues, debugging and slow deployment.

Maintenance hell is a symptom of the frameworks in use, not Lambda. If you’re using stable tools, you can go years before doing a 5 minute runtime update and then go years.

Debugging and deployment speed are a stronger argument - the best balance I’ve found is to mandate modular design and local development so developers can work locally except when they are troubleshooting environmental interactions. Framework complexity also matters here - if you’re deploying a heavyweight app using AWS SAM your deployments will be at least 1-2 orders of magnitude slower than a simple Lambda.
