Your zoom is hitting its limits in low light
In darker scenes, you are often already wide open and raising ISO or slowing shutter speed. A faster prime near your usual focal length could give you more room.
83% of your low-light photos (190 of 229) hit the lens's limit. You're also pushing ISO 3200+ on 49.5% of shots, while only 10% were shot at f/2.8 or wider.
