forgot about arena, whoops,

normal arena is more about damage so anything that has extra normal hits and damage is usually all that matters, Iris for eg, 7* extra skill has extra normal atk hits, Selena with Lexida, has extra hits as well as Angel Idol buff. For colloseum that is more tricky and i myself dont play colloseum arena much so cant really help you there.

And for sphere setups, you would want the special spheres for the specific units that requires them for extra skills, like Dandelga for Avant, Glacial Staff for Haile...etc Refined Jewel ( or any status negate sphere) on status cleansers is a must in most cases, but since rinon extra skill negates them, it frees up for other spheres.

For damage purposes, spark spheres are generally better as most late game contents have crit damage resistance.
