In the end I ran out of time and had to make a decision and the PANASONIC TZ40 (ZS30) won.
It was a massive compromise on many levels. It was a huge shame not to have RAW, nor a larger sensor, but I did want that telephoto ability (with a good image stabiliser), plus of particular interest in the absence of an articulated screen instead it has Wi-Fi control by a mobile phone. It also has High Dynamic Range which compensates for no RAW (probably only a bit!). Anyhow that was my decision. I will prob buy something else in another 2 or 3 years when the technology has moved along a bit.
