Now, here are the similarities between Jack Frost and Cirno you were looking for.

Both of them are members of the Fairy race who are mainly affiliated with the ability to manipulate the element of ice. Whilst fairies are normally considered to be one of the weaker/more common species in both SMT and Touhou, Jack Frost and Cirno manage to stand out above a majority of the cast as two of the most iconic and recognizable characters of their respective franchises.

Both of them are known for having exceptionally large egos and mischievous personalities, which in turn leads them to pick fights against Demons or Youkai that are generally well above their weight classes. However, unlike most other fairies, Frost and Cirno have at times proven themselves to be able to stand on even ground with many of their franchise's heavy hitters, which held especially true when they were given the lead roles in their very own spinoff titles. Or at least an officially promoted fangame in Frost's case.
