yasnippet-snippets VS yasnippet

I second yasnippet, it is extremely handy for all sorts of boilerplate (like LaTeX preambles, environments). There are many contributed snippets in the yasnippet-snippets repo that you can look at as examples.

But you could look at what others do for Yasnippets? https://github.com/AndreaCrotti/yasnippet-snippets/tree/master/snippets/emacs-lisp-mode

You may want yasnippets. It's in melpa. I don't use lsp-mode. Consider using gnu global with ggtags and ctags for parsing and indexing your code-base for searching for symbols within emacs.

There's YASnippet, which could be used in much the same way as the tools that were described.

Although the Org manual says that YASnippet doesn’t play well, I personally haven’t had any issues. Maybe I’ve just been lucky? But I do have a snippet that uses the format command to create an Org inactive timestamp. Just a thought.

Hmmm... Maybe yasnippet?

Yasnippet might work. It's mostly used for programming related expansion, but I see no reason it wouldn't work for this too: https://github.com/joaotavora/yasnippet

Ah the code generation in the gif is from a plugin (Yasnippet) for the main editor I'm using (Emacs) to write GDScript. So not the built-in editor in Godot, no. The only bits I wrote is what keys expand into what on top of the snippet language, but they're just dumb text expansions and are unaware of any language specific context, e.g. this is the map one:
