I usually recommend a concert scale for newbies, & I still do, but in your case, you have basically found out what you like.
I spent most of my first year on a Kala KA-SLNG long neck mahogany laminate uke, it was perfect for me starting out, & I still have & use it 2 years later.
But if you want to spend more money, my best uke is a long neck concert solid acacia Opio, & they do a lovely soprano long neck.
If you want to hear how it sounds, there are videos of it on the internet, as well as one of our members' video, available in another thread.
P.S. You can put a low G on a long neck, no problem, to increases your finger picking opportunities.
