While [name_f]Lauren[/name_f] is a bit mainstream to me personally since there were so many in the 90’s you could however say it is an underused classic now. If you love it you should use it! [name_f]Laurel[/name_f] is a fresher name but I do think [name_f]Lauren[/name_f] fits your middle and last name better.
[name_f]Laurel[/name_f], 100%.
Fresh, familiar and floral. Can’t beat it.
