I'd say that for any child, autistic or not, working from their strengths is a good approach.
I know for myself that being very good at certain things preserved some of mye self-esteem when I got older and started becoming aware of my social difficulties.
Autistic kids can be strongly motivated by their special interests. The special interest can become a platform from which to learn other skills, such as interacting with people and self-organization, if those skills become necessary for taking the special interest to a higher level. I know your daughter is small now, but it's incredible how fast these years pass, and she is entering the age where her interests will become more complex, although this depends a bit on her personal level of maturity.
I see other parents struggling with their neurotypical children, and what is obvious is that forcing kids to behave in a certain way tends to backfire, NT or autistic.
