I'm not sure how people typically use neovim, but in Zed I find multiple cursors (especially combined with multiple file buffers) extremely ergonomic for refactoring quickly and easily where tools like find and replace or simple renaming doesn't suffice. It lets you scan through and add cursors where you need them, then perform your edits across locations and even files all at once. It's so nice that it played a sign…
I am so used to sed-style, regex powered find/replace, that this use admittedly never occured to me. As a result, multi-cursor seemed mostly useless outside of pair programming that I never do. I will have to try it out once it lands in neovim just to see if I can wrap my muscle memory around it.
It's entirely possible that you don't need multiple cursors
