I wish we could get arranger keyboards with nothing on them with thousands of styles on a disk that we could choose and load ourselves.

Boo - we're THERE already! There are so many styles out there - just make a collection of the stuff you like and start saving whole blocks of them in your keyboard. Even my lowley i5S has 64 custom memories that I can constantly reload with new styles if I choose to. On my old G7 - you could wipe every style that you didn't need and replace it with a new one! There are others too, that do this.
I don't believe that there is ONE keyboard that is best for jazz, and one for rock etc. they all have a taste of all genres and most are pretty competant - it you play them right. There is a science to "arranging" on the fly and simply playing the right chords doesn't cut it. The very nature of jazz is improvisation, and it doesn't lend itself to "machine like" rigidity very well.remember - it's all a compromise. We're all just trying to sound as good as we can, but the machine is still the weak link. Learn how to exploit the weakness.....and you'll create a great product!
