My quilt weighs about 25oz. 10F, long, wide from Underground Quilt. I would go with 0F if I was getting another one. I'm getting old enough to feel the cold more. You always want the widest they make to keep it tucked in, especially if you're a side sleeper like I am.
UNDERGROUND QUILTS UGQ 0 degree F Bandit quilt with Exped Downmat 7. If I need more I add clothing layers.
This. A quilt is a good way to achieve the OP’s goal. I have EE and UGQ down quilts, and they are both excellent. A 10F quilt with NeoAir XTherm MAX pad makes a pretty good setup for the conditions you describe.
