Lol no need to reroll a redguard as you have nice synergy between nightblade your race and playstyle any way. As a wood elf you have stamina regeneration perks and the sneaky racial perks which means you hit harder from sneak so you certainly do not need to reroll. You obviously enjoy the archer playstyle so it's a given your bow is on the main bar and the choice for backup comes down to what you feel is important to add to your build. In its most simple form:

2h you are adding the rally self heal and 20% weapon damage buff as well as a gap closer in critical charge and obviously wreaking blow a high dps single target

Dw you gain steel tornado which is a great aoe attack and flying blade which also adds the 20% buff as well but requires hitting the target

S&b you gain extra defence from the extra armour slot plus blocking passives so is the most defensive choice by far as well as giving you defensive stance to bounce projectiles back at people

Resto staff would fill the gap nightblade have with reliable self heals but as your mostly stamina based you would not get the maximum benefit but hitting your cloak and spamming the heals is a nice way to reset the fight in your favor

Destro staff in my humble opinion would be pointless as you already have ranged damage and the staff would be weak due to lack of magicka

Hope that helps you make a decision but the best advice I can give is to try a few things out during the levelling process and see what you prefer
