There are three different options for you, in my opinion. The Pixel 2 easily has the best single shooter around, and does some incredible things on the software side. It doesn't have RAW support, however, but I'm sure you can remedy that. The LG V30 can't compete with the Pixel 2 in straight picture quality, but it has every camera feature imaginable, is a fantastic video performer, and the wide angle camera is a boon. Then there's the Huawei P20 Pro, which has an insane tri-camera set up that can easily produce some fantastic shots. Based on what you've told me, the P20 Pro might be the way to go. I think you can ween a better photo out of the V30 and P20 Pro using their manual controls and with RAW support, but for a casual shooter absolutely nothing beats the Pixel 2.
