Here’s another experimental order, heavily inspired by ScreamsInTheVoid’s post above. For this one, the focus is on a more “modern” introduction to the franchise for newcomers, while still showing the entire franchise as-is:

Andor (gradually introduces the classic Star Wars concepts in a more mature, modern way)
Rogue One (resolves Cassian’s story, and sets the stage for the OT)
A New Hope (the most natural follow-up from Rogue One)
The Empire Strikes Back (the most natural follow-up from ANH)
The Phantom Menace (begins a lengthy “flashback” series after the ESB revelation)
Attack of the Clones (the most natural follow-up from TPM)
Revenge of the Sith (the most natural follow-up from AOTC)
Obi-Wan Kenobi (bridges the gap between ROTS and the OT)
Return of the Jedi (resolves both the OT and flashback plotlines)
The Clone Wars (fleshes out the flashback timeline and begins the “Filoni-verse”)
The Bad Batch (the most natural follow-up from TCW)
Solo (only here because I didn’t know where else to put it)
Rebels (continues plotlines from TCW and sets up new ones)
The Mandalorian s1-s2 (continues plotlines from TCW and Rebels)
The Book of Boba Fett (basically season 2.5 of Mandalorian)
The Mandalorian s3 (the most natural follow-up from BOBF)
Ahsoka (continues TCW and Rebels plotlines even further)
The Force Awakens (the start of the grand finale)
The Last Jedi (the most natural follow-up from TFA)
The Rise of Skywalker (the “end of the franchise”, both thematically and chronologically)
