HELP with my FILTER + SORTBY FUNCTIONS

Boulakgnobot 

I think I have two distinct exercises muddled in together but, for what it's worth, my approach is to develop a solution step by step, aiming for a readable syntax.

= LET(
    Joinλ,   LAMBDA(s, TEXTJOIN(" ",,s)),
    females, FILTER(names, gender="F"),
    sorted,  SORT(females, {2,1}),
    fullNms, BYROW(sorted, Joinλ),
    WRAPROWS(fullNms, 6, "")
  )

1. Define a Lambda function for use later

2. Filter the array to return females only

3. Sort the names by surname first, then first name

4. Combine each name to a single string

5. Reshape list, filling with blanks if required
