Getting a £2000 camera (even £1000) and leaving it on auto is like getting a Ferrari to drive in a 20mph area.
I noticed you also posted in the Photography board. Honestly, the advice to stick with a phone and/or some kind of iPhone is probably your best option. They've been specifically engineered to squeeze out the maximum quality and convenience in the space given. Is it going to beat a dedicated camera? No. It's a do-everything device that's like 12mm thick. Where exactly is it going to fit actual high quality components that compete with DSLRs and the like? Will it give you decent results with the least hassle and taking into consideration the size? Sure.
The way you keep mentioning "auto auto auto", auto camera settings, auto RAW processing magically make beautiful with 1 click; photography processing and video processing doesn't work like that. People wouldn't be able to make careers out of it if it were that easy.
The Sony Pro-I you mentioned I would not recommend for you. Sony phones are a bit weird, in that they're almost designed with an expectation that you'll do some kind of post-processing to get the most of them, be it with the videos or their photos. Their auto modes are said to be quite poor compared to the competition.
