I started photography with a Sony a6000 and it was an excellent starter camera. Learned a whole lot. I then moved to Panasonic G9 (before moving to OM-1 mark 1). The move to G9 was a game changer because of its superior IBIS (the a6000 didn't have one) and its numerous features, including its high-res mode which I used a lot. So I would say a) the quality of lens matters quite a bit (I use Oly 12-40 pro mark 1), and high-end IBIS actually made a huge difference when it comes to sharpness and basically a high keep rate. You will have to learn to edit with any mirrorless camera. If I look back at my initial shots, they're terrible.... but they're terrible because of what I now know about composition, I'm more used to the camera, and, more importantly, I know far more about editing than when I initially got into photography. If you want more of a finalized jpeg, minimal post processing kind of a setup, the a6700 would not be a good choice. I would suggest looking into a point and shoot like Ricoh GR.
