Regarding the distraction, IDE can also turn off most of the features that you do not need to let you free from distraction, so you do not have to use Notepad, vi or ed to avoid idstraction.

When you say you work with very large projects, do you mind sharing an estimate of how many LoC (a poor metric, but still), language and contributors your project has? From my experience, when you do not have problem with bulk refactoring, either your project is not big enough, or do not have many change or no so many contributors so that any kind of replacement with review is not a significant issue. In these cases, it's hard to see the benefit of features offer by IDE/LSP. Just like when do you see bubble sort and quick sort have similar performance? When there is only a few items in the list.

And finally, I also an Emacs user, so I ask you to experiment one thing: instead of using find-grep, try consult-ripgrep and see what improvement it offers compare to find-grep. And remember that an IDE can do even better than that.
