Affordable Black Oxfords
I would never wear Florsheims even if you gave me $50,000 worst shoes I ever wore in my life.
Kind of an extreme position. Florsheims may be shite shoes but I would wear them if you paid me $50,000. I would be happy to go spend that money at John Lobb, St James.
I would also consider black captoes from Andrew Lock, Meermin, Loake, Herring etc but you won't really be able to try before you buy and they will be a little above your budget.
I would choose the Edgar out of all of those because they are closed-laced.
Just be aware that they are probably corrected grain and won't last as long as a full grain leather shoe. Unfortunately, I just don't think you are going to be able to get something full-grain and non-AE at your price point. Maybe Loake is the closest to what you want if you are not adverse to buying online, but you are still looking at around $260.
