You are unlikely to get amazing dimming performance using constant current with a 24V strip intended for constant voltage operation.

For a bench application like this, get a constant current strip from Bridgelux. They’re cheap and excellent. Digi-key sells them. The “thrive” series is a bit less efficient but has a very nice spectrum. The tiny drivers from Cuvee Systems work well, start quickly, and dim well, but any ordinary LED driver can drive them. Or the bench power supply :)

For 24V tape, here are a few decent choices for drivers:

The Meanwell PWM series. The frequency is below IEEE 1789 recommendations but is okay.

eldoLED LinearDRIVE. The best, but kind of expensive and annoying to use. Program it for a log curve. Here, for example:

These are convenient but massively overpriced:
