As another fan of Kakoune's model of editing (or model of modal editing), I would recommend Helix. It's a low-config tool that lets you start working without turning many knobs. Supports tree-sitter grammars and language server protocol.

I haven't heard of either Kakoune or Helix, but I'm buried pretty deep in my own opinionated config.

As far as I'm concerned, the more readymade options, the better. Thanks to you and sevensor for adding recommendations!
