Another vote from me for Lenovo - mine is a Yoga. Keyboard is pretty good although there is a bit of key bounce occasionally, battery lasts about 6 hours if I'm not using any heavy applications (and it's fairly hight-end processor). Certainly light and portable. Can handle graphics/video/publishing tasks without difficulty. Haven't seen built-in Ethernet for years, my model has 2x USB-C and that's it - plenty of nifty little hubs available now, I have one with a couple more USB sockets, card slot, HDMI (and, I think, RJ45).
Having said all that, and I hope this doesn't fall into the bloke down the pub category, a friend swears by his MS Surface which offers tablet portability and pairs with a keyboard base which turns it into a very competent laptop - I haven't used it myself (although I've shared an office with him and there's no doubt that he's productive with it) but he's quite discriminating when it comes to such things and he's very happy with it.
