Best/low maintenance devops toolchain for basic sass?

I'm looking for a new devops stack, I got pretty deep into k8's, and I feel like it's just too much overhead. It is cool, and does a lot of great stuff, but it seems like there are other solutions that are better for basic sass app type stuff.

I start a decent amount of projects, and so I'm looking for something that's fairly low maintenance. I know nothing is 0 maintenance, but the less the better. I do lean towards AWS, but I wouldn't mind flexibility in different cloud providers as well. If a solution is really elegant though, only supports one provider, i could get behind that.

I've been doing a little research, and these are some of the options I'm considering.

1. App engine/Elastic beanstalk with terraform 2. cloud formation, with lambda 3. CDK, with lambda and api gateway 4. serverless with CDK 5. SAM 6. Some other combination of the above technologies.

The only requirement I have is that I should be able to develop offline. I can't stand having to be online and deploying things in order to develop / test.

Currently, I'm kind of leaning towards serverless with CDK (if I can use CDK offline). Anyone have any experience with that? Did you have any long term issues or drawbacks?

I typically also use hasura with postgres as well, so I don't want some premade firebase type solution
