You can’t formulate a plan until you know exactly what you’re dealing with. A solid evaluation will map out her strengths and weaknesses and offer advice on accommodations and such. Ideally, you take those strengths and nurture and use them to cope with and work around the weaknesses.
If your child is struggling at all (including with self-esteem), that’s the time to get the evaluation. In addition, evaluating when she’s on the younger end means you may catch some issues that haven’t been a huge impediment yet, but may become one if not addressed. The earlier “treatment” (not just medication, but therapy, support, accommodations, etc) starts, the better the long-term outcomes.
