j gilbert. Ask for Yenni Song.
Also Leathersoul has make-ups in plaza and other lasts.
Trubalance goes the other way: it is the last the indy boot is on and is Alden's widest last -- widest all over, including toe box.
You want plain toe on plaza last.
I would go LWB or straight tip/medallion toe
In this order: (1) Captoe bluchers; (2) perforated captoe balmorals or (3) short wingtip balmorals.
Personally, I would opt for the NSTs because I love the NSTs. I recognize, however, that given the restriction of one pair of color 8 cordovans, the NSTs are an idiosyncratic choice for suits. Most would think (and most would likely be right) that the other three choices above would have more versatility along the range of clothes you specify than NSTs.
