I have not tried any of the boots you listed, but a week or so ago, I did try on some boots at the local Clark's store - some flat boots and some boots with a slight heel. Amazingly, the Clark's "Cardy" boot (the heeled boot) was the most comfortable of all. I was in shock, as I'd assumed that flat boots would be more comfortable. These particular heeled boots aren't fancy, and don't have lots of interesting details - aside from a little tiny sort of leather braiding up the sides, but they were sooooooo comfortable. I didn't buy them, but I'm "stalking" them, just because they were that comfortable. Really nice boots!! Simple, but good.

Having done a little bit more research on these particular boots, they claim to have some sort of fancy footbed with 'active air technology' or something like that. In any case, these were ten times more comfortable than umpteen flat boots I tried. Just for the record, I measured my calf - and it's 14.75" at the widest point. When you say wide - are you referring to calf measurement or just the shoe part?
In terms of the flat boots I tried, the Bandolino Castalina was also pretty darned comfortable, but I felt like the calf was a bit too wide on me - they aren't super wide, but they are slightly wider than some others I've tried. I'm not sure I'd call them 'dressier boots' though. Here's a link to them, just in case - they seem similar to some of the ones you've linked.

The Bandolino Castalina boot is on sale at Macy's until midnight tonight, for $104. They are higher in the shaft - and wider in the calf as well. Like I said, not super wide, but definitely (slightly) wider than something like the Ecco Bremens or Clark's Cardy. The Bandolino Castalina boot is very nice-looking, and comfortable, but more 'equestrian'. What I liked about these is that they came up higher on the shaft. Not to the point of being annoying or anything, but better than some other 'knee high' boots that aren't all that 'knee high' after all (on me).
Meanwhile, in terms of a boot with a slight heel - I'd have to suggest either the Ecco Bremen tall boots (only available at Dillard's right now in the black leather $159 - I think it's a style from a year or more ago), or the Clark's Cardy boot (approx $200 just about everywhere). That said, I'm still working my way through the boot conundrum myself, and haven't yet tried tons of boots on.
