There are many possibilities. You could use 18:18 ; 15:21 or 15:24 build.
WPF with 6 or more WM, you could use around 100 in onehanded and aroujd 120-130 in xbow. Deoends which weapon you want to use mainly. Hunting xBow, +3 is good damage, +0 indeed shitty. So as 1h weapon, I would choose a steel pick or some other pierce weapon. If you want to use a sword amyways, I would choose Short Nordic War Sword, damage is good, 0 slot, by the wwy and a great speed.
To your edit: It depends on your playstyle. If you want to be fast, use a medium or light armor. Maybe you can find an armor, which has enough body armor and less weigth. You want to be meoee fighter as your main playstyle, you better use medium-heay armor.
