helm-swoop VS lispy

I am thinking myself of whether swiper/swoop functionality can entirely replace isearch, or whether it is better kept separate. You never use isearch at all?

Helm-swoop https://github.com/emacsorphanage/helm-swoop

The easiest way of doing this is using M-x occur which might be bound to M-s o by default. This will involve typing out the search string. I like using helm-swoop which I've bound to M-i, which searches for the thing at point, which is faster. Both of these tools generate the sparse buffer and let you jump around the file. The advantage of using occur is that you can invoke edit and then modify one or more occurences directly in the occur buffer.

Some killer features in Emacs, which I would recommend checking out, is imenu and movement by s-expression (functions like forward-sexp). These are built into Emacs and make navigating across or inside blocks of code very easy. I have also seen that lispy, which is usually used for Lisp code also supports Python. Again I can't speak to any specifics about how well these things work for Python devs.

While writing other programming languages with LSP, it formats the buffer once I hit save. Is there any way to make https://github.com/abo-abo/lispy do some equivalent behaviour?

Without any order magit, lispy and minions.

I don't know cider, but...I found lispy mode a revelation in making the easy, easier.

The level of interactivity in your emacs determines how easy trying emacs-lisp becomes. I suggest checking out https://github.com/abo-abo/lispy, it makes it easy to look up documentation (C-c 1 I believe) and evaluate S-expressions on the fly (keybinding is e). Also C-h f, C-h k, C-h v are always very helpful. Also check out helpful (the package), selectrum, marginalia, prescient, etc.

Emacs seems to attract quite a lot of people who want structural code editing. We now have * paredit * smartparens * evil-cleverparens * lispy * symex * combobulate (more?)

Obviously, we have packages like Paredit and Lispy, recently we got SymEx, but these are all for the Lisp family of languages, where syntactic redundancy is very high because of the homoiconicity.
