I've been using emacs for a decade by now.

I'd look into spacemacs (what I use).

It's similar to doom, in that it makes some decisions for you, but you can very much have a customized experience.

I for instance have a lot of "stock" sections, and other things that are very customized that I've made myself.

Look into the "layers" (sets of packages that work together). I'd particularly recommend checking out the compleseus layer, which is a composition of consult, orderless, vertico, and embark.

They're all built to be composable (selection, pattern matching, selection interface, and context menu respectively), and they each add up to a brilliant emacs experience while reusing emacs' built-in frameworks (completing read). It's an alternative to helm and ivy (I've used each before).

The reason I recommend spacemacs (I'm sure doom could be the same, I just didn't know it) is because it is an easy way to see what packages other people find useful and how to use them, and it has similar conventional across different packages (so you can run tests in the same way no matter whether you're using rust, or python or whatever other language).
