All of my dimmers are Inovellin Gen , LZW31-SN, which are leading edge, and does not have a parameter to switch to trailing edge, as far as I can tell from my search today on their web site. I know LEDs often want trailing edge, but I'm not going to just swap out my 20+ switches for that. The lowest I can dim is about 25%-35%, using mostly Ecosmart 60W, 5000K, 840 lumen bulbs. My wife likes them normally really bright and daylight so I'm looking for similar specs.
I also don't know if it is possible with dumb LEDs, but can any that get that bright be dimmed low enough so they get that orange-like glow of an incandescent?
This is just a property of how the incandescent filament glows, not the light level per se. In the early days of LED bulbs, I remember some manufacturers touting the fact that their LED bulbs don't do this (i.e., that they do maintain a constant color temperature as you dim) as a feature. What you're really looking for isn't something that can dim low per se but rather something that intentionally simulates this behavior (and, I suppose, can dim however low you need).
The above from @hydro311 is the only one I've heard of, but I'm about all in on smart bulbs at this point (certainly another option, probably not the cheapest) so I haven't looked in a while. In any case, if you search for something else, it may be helpful to keep on mind what you'd actually want to look for feature-wise, so hopefully that helps! You aren't likely to find many since, again, this is a feature they'd need to bake in, unlike incandescents, where it just happens.
Not for dumb dimmable LEDs. Temperature stays constant through the dim range. Don't know about your dimming switches. But the ones I use, the driver has a min dim level needed to get them to glow at all. That exact setting depends on the LED devices. But I find that setting to be 18 to 22%. That sets the 1% level for normal dimming. For which can be so low I can see a glow only in a dark room. So check your driver and is it has it, set the minimum to what ever you want and that will become the 1% dim level for your actions.
