Courtney Barnett is great if you’ve not listened to her yet, although she can be somewhat polarizing stylistically. Sharon Van Etten sorta has a similar vibe to me.

First Aid Kit leans a bit country/folk sometimes but I’m a huge fan personally.

Not sure if you’d count KKB, The Japanese House, or Fiona Apple as they all tend to lean a bit more into other genres, but they all are pretty good.

Harmony Woods is a kinda smaller Indie Rock band that i also really enjoy. I will say though, they’re much better live than on their albums.
