My personal preferences:
Rapier/Longsword/Cutlass - Manyullyn blade, Paper guard, Thaumium handle; load with full Damage (quartz) unless you want something like Looting (lapis) or Vampiric (necrotic bones).
Which one of the swords you pick is really personal preference. Rapiers do less listed damage, but are armor piercing and especially fast. Longswords don't let you defend, but gives you a leap "attack" for added mobility (jump up to 4 blocks if you time a jump+leap properly). Cutlass has a built-in 10% crit chance and if you block an attack, gives you a short speed buff.
Arrows - Thaumium head, Paper shaft, Feather fletching; load with full Damage (quartz) unless you want something like Looting (lapis) or Vampiric (necrotic bones).
Bow - Green Slime rods, Magic Cloth string(TC3) or Flame String string(TC4); load with full Speed (redstone) unless you want something like Knockback (pistons)
For adding enhancements to arrows, make sure to make a full stack of them first, you can enhance them all simultaneously. Mind you, you don't really need arrows this powerful for much outside of boss busting, but still.
