Offhand, the regular Swift 3 for budget and the Swift 5 (14") or Samsung Galaxy Book2 (13.3" or 15.6") for built well thin and light models with oodles of battery without dedicated graphics. There are a few others but these are my favorites, and I have personal experience with all of them. The LG Gram costs a ton more and also has a thin/light 17" model (3 lbs), but tends to be wildly expensive and I have no personal experience of them.
If you are ready to buy, I'll do a quick scan of the sites and find you the best value.
