There are lots of people on this board who don't like jackets and are back-inflate or BP/W fans. Personally, I see nothing wrong with a well fitting jacket if that's what you like, though if you are doing some diving in cold water you may eventually find some sort of back inflation preferable to a jacket.
Most of the things you say you prefer seem to be reasonably well considered choices for now, except for 2 things I would think about a little more-
As far as the squeeze of a jacket, while some people like the "hug", more people seem to consider the squeeze a negative and move away from jackets for that reason. I actually don't see how using the amount of pressure you feel as a way to judge buoyancy is any kind of reliable method, in fact I'm not sure I've ever heard of someone doing this. I suspect it's something you will (or should) get away from. As mentioned, in warm water people tend not to have much air in their BC, and it will usually be behind you and won't be squeezing you - so if you're using enough air to feel a squeeze from a jacket in warm water especially, it does sound quite possible you're overweighted.
And while some people do like Air2 type alternates, they have a lot of drawbacks that are not immediately obvious. If you not yet read any of the many discussions here of their pros and cons, I would suggest doing that before making that choice.
