I got curious about this and found https://github.com/danr/kakoune-easymotion which I'm going to give a try.
I haven't tried helix in a while, sometimes they have chosen not-quite default-kakoune like bindings which trips me up for certain kinds of selections.
There are a few plugins I cannot work without. It's nice they have tree-sitter and lsp out of the box, but I can't live with things like hop[0]
