All you kinda need to know is that empire bad but that is glaringly obvious. I have commented about this before but Andor benefits from not having to carry the baggage of the star wars canon. Specifically, the stuff in the three movie trilogies is completely irrelevant and it's for the better. The movies have an incoherent metaphysical chosen one narrative that made for good spectacle 20 years ago but it goes against the themes of Andor.

Andor is my favourite TV show ever for a lot of reasons and the fact that they chose not to say jedi, sith or force anywhere in the first sesson (haven't watched the second one yet) is somewhere near the tippy top.
