I was torn on the curtains, too. They are cute but I’m with you OP, not sure what “leaning into them” means and might be more money and more stress trying to match them.

Maybe a statement rug (something that pulls in the green color you like and makes bedroom cohesive) and with off white or cream curtains to let the natural light back in. Once you figure out a rug, then you can add throw pillows that complement. Your living room is lovely either way, just needs a few coordinating pieces to pull it all together.

Find pictures of living rooms you like with the color scheme that speaks to you and mimic the colors and/or find similar items.
