I am fairly sure the purpose of the ribbons was to make Emma and Elsa love her again; she could clearly cast the curse with her own power as she did so with Anna. She could poof too; by your logic, Pan's magic was also limited to fairy dust and Neverland nature, because we never saw him doing anything else. There's no reason to believe Ingrid's magic was limited to her ice powers, whilst there is reason to believe it isn't; the fact that Elsa couldn't do several things Ingrid did. Ingrid was a full-fledged witch. Maybe not the memory magic, but she does have telekinesis, poofing, immobilization, etc. We just never saw that to a great extent.

Yes, speed is a thing, but a sufficiently powerful sorcerer can break a spell done by another, as evidenced by Regina breaking Cora's immobilization.
