String is a Type which may contain characters. String is a synonym for ShortString or AnsiString depending on the current compiler setting.
If Compiler switch {$H}/{$LongStrings} is on {$H+}/{$LongStrings ON}, then a String type is the same as an AnsiString type, if not, it is a ShortString type.
The ShortString length can be decided by the programmer but is limited to 255 characters. If a ShortString length is not given, the length defaults to 255.
The length of an AnsiString is only limited by available memory.
In the future, there might be a compiler switch to have the String type refer to a Unicode (UTF-8 or UTF-16) String type.
