AliExpress has some of the best leverless controllers out there, and it also sells other kinds of controllers that you should check out.
The wireless IINE HB1 has a rare left ring-finger button, but you can cover it (and any other button) if you want.
The Haute42 V16 Future White has all big buttons, and its LEDs allow you to see it more easily in the dark.
The Haute42 Emotion III-17 has four thumb buttons, a couple of which are pill-shaped, and it has a left pinky button (plus a lanyard loop).
The HauteBox Zero is a 14 button ergonomic controller that utilizes Wind Engine switches and is made of metal.
The P12 Pro-Remix is Haute42's third rendition of this controller, and its interpretation of the retro Nintendo aesthetic is quite faithful.
The R10-Pro is an arcade stick with a trackball and spinner. You can also buy the R9 with just a spinner and the R10 with just a trackball.
The X-Move is a sequel to Haute42's modular controller that was nominated for an Evo award, and you can move some of its modules sideways.
The R8-SF2's Happ joystick and buttons in a straight layout let you play games like SF2 like how they were played decades ago in the States.
