Hm I think perhaps this conversation, somewhat inadvertently, is actually talking about two different things, myself included. I do still think that flatter, funkier light metallic shoes could be a fun option for you but NOT in the place of the booties you later brought up; I meant in place of the gold pumps. So my metallic examples were more in line with those, and the effect that they would have in an outfit (and the finds I included were my own shoes, not necessarily shoes I would suggest for you specifically).
I'm glad you left your ramble in! Specifically this line: I think it is the “texture” part of that boot’s effect that appeals to me, more than the “glamor” aspect. To me this is a very important distinction. I did go back and look through the boots, and they seem in line with this line of thought. However the vibe I get from them is more a bohemian feel -- rich color, texture, maximal details, and actually a fairly refined overall look with a little dark glamor.
Do dark metallic shoes work like dark shoes, or does the metallic make them work light? They will work like dark shoes because they are dark. Just a little less severe then, say, solid black, because the metallic sheen lightens the boot a little. Not enough to be low contrast, though.
So! I will change my recommendation a bit
Re the boots: I think they will be a very good fit for you, kind of like a boot version of the new loafers you've been wearing a lot. Short ankle boots are great for FL winters and based on the pieces you've listed I think should work quite nicely. They will NOT behave like a light metallic shoe and I don't see any overlap in function there. As I said above, they should work anywhere your loafers do when you want a more boot-y look (and could be particularly fun with shorts/capris/dresses if that's a look you like).
Re the gold loafers: I vote hold off for now and experiment with the light shoes you have to see if you even like the "nude shoe" look. You may find that you don't feel the need to lighten up a look and that's just fine! If you find that down the line you are still thinking about them, however, then revisit the idea and look at what specifically is the appeal; I don't see this particular pair as quite in line with what I've seen from your style. Of the four light colored shoes you linked I think #2 and #3 look like they should work well for you along with the boho sandals.
