Pyinstaller can be a bit fiddly to get right initially if you have a lot of package dependencies, but other than that it works really well.

Using the spec files for persistent readable configuration also goes a long way, if you treat pyinstaller as a python module you can automate it whole with just python, including the spec files as it executes them as python scripts

I've had automated builds running mostly untouched for years here https://github.com/Numerlor/Auto_Neutron/blob/master/pyinsta..., though it doesn't have any particularly troublesome packages other than PySide6
