String Predicates in Effect: Use Basic Predicates or Schema for Advanced Validations

Does Effect has predicates for strings? or just basic ones and we should use schema for everything else?
Like

Predicate.isNonEmptyString

Predicate.isNonEmptyString

? or

P.and(P.isString,P.trimmed)

P.and(P.isString,P.trimmed)
