George Lucas had always intended for the original Star Wars film to be a small part of a much larger story. So just because it was the first film to be released doesn't mean it's the start of the story. Instead of going with release order, you can also try chronological order based on when the movies are supposed to take place.
This would mean starting with Episode I, II, and III of the prequel trilogy, before moving to IV, V, VI of the original movies, then finishing with VII, VIII, IX from the sequels. If you're adding the standalone films, you can fit Rogue One and Solo in between Episodes III and IV, and it should work fine.
However, since this order completely ruins the Darth Vader reveal in the original films, it is not advisable that anyone should watch these movies for the first time in this order. Watching Star Wars in chronological order is more of a fun experiment for longtime fans to see the series from a new perspective.
If you were to watch the Star Wars films in chronological order, it would look like this:
Star Wars Episode I: The Phantom Menace
Star Wars Episode II: Attack of the Clones
Star Wars Episode III: Revenge of the Sith
Solo (optional)
Rogue One (optional)
Star Wars Episode IV: A New Hope
Star Wars Episode V: The Empire Strikes Back
Star Wars Episode VI: Return of the Jedi
Star Wars Episode VII: The Force Awakens
Star Wars Episode VIII: The Last Jedi
Star Wars Episode IX: The Rise of Skywalker
