I would guess that many devs' preference would be for a larger standard library, but not a kitchen sink.

Personally, I'd be happy with a larger suite of utility functions (say, most of Lodash / es-toolkit - remove the need for left-pad silliness), probably SQLite bindings (having a good persistence layer is great, it's perhaps the most robust and most widely deployed software on the planet), but not YAML (complex, security concerns, parser differences) or image handling (again, security concerns).

Node.js is, IMO, actually pretty good these days; they're regularly adding useful built-in tools that remove the need for add-on packages. (The ecosystem is so big that getting those updates to filter out is hard.)
