I have an idea for making a Half-Elf swordsman who Takes advantage of the Half-Elf FCB For slayers and I would like to optimized this Build as much as I can well not multi-classing

I am unsure of what Feinting method would work best. sword play / upset looks cool thematically but would it work well.

I also am unsure of several other things.

1: I am unsure of his weapon
2: how should I get combat expertise (Via a ranger combat style and skip having 13 INT or not worry about cha and get it from having a good INT score and bluff via the clever wordplay trait?
