In A New Hope that officer says they went to Dantooine, but it looks like it’s been deserted for some time. I say it’s a possibility, if they’re going for that nostalgic factor, which they did in The Mandalorian, by heading to Mos Eisley, etc.
Another possibility is Bestine, from the Luke and Biggs deleted scenes talking about making contact with the Rebellion.
It would be cool to finally see those places like Dantooine and Bestine in live action.
