I just did some googling and and I found this: https://github.com/godotengine/awesome-godot

No, i don't really have a general advice for that..all depends on what you want to build. I'd say start simple but as it grows you have to make sure your architecture stays clean, otherwise the whole thing becomes unmanageable. If you want to look at other big open source applications done in Godot look at Pixelorama and MaterialMaker (this one even got an Epic Mega Grant). There is also this list with great apps/pluings etc: https://github.com/godotengine/awesome-godot

The Awesome Godot GitHub Repository has some Template content, some Demos, and some Games (some of which point to GitHub repositories with source code).

What kind of content goes in the list? Is it limited to just GDScript/C#/GDNative addons that can be downloaded from the Asset Library in the editor, or also projects that can be downloaded from the Asset Library in the project manager, or also modules that require recompiling the engine? Is this a general-purpose list like https://github.com/godotengine/awesome-godot is?

Here you go, that's the gold mine: https://github.com/godotengine/awesome-godot#tutorials

I would recommend you to look at this list of plugins and scripts. There are many nice plugins listed.

For some context, I'm an experienced (~10 years) programmer starting to dabble in game development. I'm learning to build various systems to gain experience and understanding, and recently I was interested in developing a dialogue system with an editor similar to what Dialogic provides.

Use something like Dialogic or (personal recommendation) Dialog Manager.

I used a Godot plugin called "Dialogic" to create it, still working on the themes and assets, so most changes made are cosmetic.

There are two great dialogue systems available for Godot, Godot Dialogue Manager, which is geared more towards writing things in a script, and Dialogic with a nice user interface, that is more artist-friendly (though direct script editing is also available). It also has more features (at least in the new version, which is currently under development for the upcoming Godot 4 and might not be suitable for production).

Here you go. You should try RC3 with this. https://github.com/coppolaemilio/dialogic/commits/main

Dialogic 2.0 is supposed to be Godot 4 ready (according to github https://github.com/coppolaemilio/dialogic)

For your second question, try looking at existing add-ons like Dialogic either for a ready to use implementation or as inspiration for how to code your own.
