Laravel. You'll get a lot of plug n' play stuff within its ecosystem. The community is at this point massive, so there's no doubt it will stick around for the time to come.
It's not a no-code solution, but the shallow learning curve will allow you to get up to speed in no time.
You can't have it all. You may achieve simplicity but it's not easy. Rails has most of what you need for a web app, and its ecosystem has many complementary subsystems and libraries. So, it's very easy to develop something fast. But, after a certain size it starts to be less and less maintainable.
Write an OpenAPI schema file describing your CRUD, and generate code with OpenAPI Generator. Download the official Postgres docker image, run it as a daemon, and configure your app to use it. Configure Nginx as your app's reverse proxy. That's it.
Easy in all ways:
- plain HTML + JS + CSS to start with, then add some simple framework like Bootstrap + Datatables for quick results
- MS SQL Express Edition or Developer Edition as backend; it has the easiest GUI-driven installation, configuration and operation (via SQL Server Management Studio) while it is still completely free
- server side programming ... not sure, for me PHP is the simplest, but this is based on a very limited view over all options. PHP is very simple because you can just use Notepad++ or VS Code to edit files, save, run - no build, no dependencies. You can run it under Windows (IIS) or Linux, configuration is minimal.
