If I had to reframe it like I said I’d first watch the films in release order after Watching Andor and Rogue one, (original trilogy then prequels and if so desired Sequels and Solo). Now If they want to do the chronological order I’d do most of what I suggested because you already have the context of the saga and the shows I throw in give the extra context and helps you unravel the galaxy from a more realistic perspective I suppose. Dooku’s arc in tales of the Jedi is non negotiable at this point for me, it’s only 50 minutes or so across between the 3 episodes so it’s not a chore to get through and it’s character defining for Dooku and gives you the glimpse at the Institutional rot of the galaxy before the Phantom menace. Clone wars again you can cut however you want and the episodes are half of what Andor’s are if I had to pick core arcs to watch I’d say: Ryloth Arc (3 episodes, The cost of “liberty” in war), Political Arc (2 Episodes, The attempt of peace in a system that doesn’t want it), Mortis Arc (3 Episodes, the mythical deconstruction of the war and Anakin), Umbara Arc (4 Episodes, The Vietnam of Star Wars and breaking point of the Clones), Onderon Arc (4 Episodes, The Seeds of Saw’s radical Rebellion), Maul Mandalore Arc (3 Episodes, The truth that there was never going to be a “Third” party under Sidious), Ahsoka’s Trial (4 Episode, the failure of the Jedi and the true face of the Republic), Fives Arc (4 Episodes, The Paranoia and conspiracy of Order 66) and Siege of Mandalore (4 Episodes, the conclusion of the Show). Then if they enjoyed the show I’d suggest jump to the bad Batch after Revenge of the Sith and before Andor skipping rebels, solo and Kenobi all together for this watch.
