Holy shit - there are so many options! Some of those nail shapes are pretty unusual and would leave hella nasty scratches (something for everybody).
In someone I’m seeing, I’d go for : Rounded, almond, mountain peak, squoval. I love colours, so very open on that front, from neutral classy to bright vivid are all sexy to me.
Glossy or creme, or metallic for sheen.
Fancy designs are fine, but I’m not a fan of things glued to the surface, or rough textures.
What do yours look like right now?
