That works, but I don't see the special relation between Spirit Guardians and Sanctuary. Any party member would be protected. And if your Sword Dancer had high AC, he/she might be not the best target for Sanctuary, which costs you a lvl 1 spell slot. I try to use it very sparsely and only in dangerous fights. It's usually easier to replace hp in or after a fight than spell slots.
Edit:
Wether Fighter or not is good is really debatable. The one point from Fighter is just one point, but it is one of several points, so 5% more crit chance. Then you get Action Surge, all armor (or at least medium armor if you level Fighter as second) and martial weapons proficiency. One crit point comes from a longbow, it's nice to be actually able to use it (if silenced for example).
