Child works slowly with simple tasks, not otherwise. Perfectionism is observed by us. Getting ready for school is slower than his younger sister. Distraction ebbs and flows. Slow and weak handwriting, although has taken better to cursive (not unlike his father (me)). Prefers to type on an electronic typewriter over handwriting. That said, he is a great skier (I guess not fine motor skills).
I would keep an eye on the fine motor aspect of things, as that can impact work completion, which can affect how teachers perceive skills, which, of course, affects their grading and recommendations for more challenging coursework. Once one reaches the upper levels, where keyboarding is the norm, handwriting is not as critical.
Cursive is often easier for kids with some fine motor or dysgraphic issues, as there are fewer initiations.
