I love
Linda for the meaning & connotation, even essence of prettiness & beauty; I also like
Belinda almost like an imperative formulation of these attributes - i.e. everything about "
Belinda" is the epitome of this definition.
I am indifferent to the various spelling choices.
I have little association with the name
Erica (
Erika), but the only magic behind any name would be your special preference for it. I hope you endear your child with it.
