You don’t need anything exotic. Speed and torque are not an issue. You just need something that fits physically. This is a Servo that has a decent price point and nice specs. It is a HV MG Servo. HV means it will operate on voltage up to about 7.4 . The MG means it has a metal gear train. Metal gears are much better than plastic. https://hobbyking.com/en_us/corona-ds339hv-digital-metal-gear-servo-5-1kg-0-13-sec-32g.html
I did all my Gauges with X27 for single Pointer and X40 Stepper for dual Axis.
10Pcs 18€ from Aliexpress . Those Stepper are used in Automotive for Speedometers. With an additional VID666 driver, you can drive 4 Stepper by only 8 Pins. Zero adjustment is included. Really simple to use.
