Well, maybe the flatpak release package would work better for your
situation; just a thought.

I would recommend first the SDK documentation. The with basic or python the
use of an object inspector extension wich can link to that documentation.
The SDK is available for download from the main site.
You can find some information about python object inspectors and editors on
the wiki at
https://wiki.documentfoundation.org/Macros/Python_Design_Guide

A lot of the 'how to' pages I find for libreoffice/python start with an
example of running libreoffice in a mode that allows an external python
application to interact with it.
However you can also use python code from within the libreoffice
application, through the macro support. When you do that then you can setup
your listeners on many things, like documents or forms, just as easily
using python as basic. Dialog boxes, as you note, is not one of them. Yes
you have to set that up in your python script when you prep to instantiate
the dialog and if you want to use the basic IDE dialog editor you have to
do a tab bit more in python than basic.

I would say, think of uno as a specification for an API and the uno objects
which service requests through the api could be written in more then c++.
(but IIRC, it has some c++ ish quirks)

I think a python/libreoffice cookbook would be a great idea, btw.
