My most frequent EDC that meets your requirements is a stainless handled Dragonfly. I have large hands with thin fingers, and it opens pretty easily. You can get three fingers on it solidly. The blade shape is very useful. The flat grind slices well and the whole knife sits nicely in your hand. The FRN (black plastic handle) is OK, but the steel looks nice and feels well-built. I'd recommend this first.
The Jester and Ladybug are a bit small to easily open one-handed. Kiwi is a little bit larger, but I still open it two-handed most of the time. The Lava is a bit large for the blade size, but easy to open and very ergonomic. I tried a pass-around Cricket and liked it. The hooked blade is good. You end up using the tip for lots of fine work, and cutting on flat surfaces. The very tip might be a bit fragile if you try to pry with it or do heavy-duty work. Sharpening is difficult without a rod-based system or Sharpmaker. I don't have any personal experience with the Spin or the etched dragonfly or cricket models.
(My other personal choice is the Spyderco Dodo. Small blade, but big enough to grab and use. Unfortunately, they're no longer manufactured, and can be expensive if you can find one. The Dodo and Dragonfly rotate back and forth on a regular basis when I have to carry in a restrictive environment with a short blade length limit. Note that the Dragonfly blade is over 2" to the handle, but the cutting edge is just under 2".)
