Should I switch from the canon eos 2000d to mirrorless?

I'd only switch if you have a reason. The 2000D still takes a huge range of lenses, and it's an APS-C camera, which is the sensor size most mirrorless cameras use. Your lenses are the expensive part, so you don't need a new body to get good pictures.

The case for mirrorless is real, though. You see the exposure before you shoot, and autofocus can find and follow eyes. Every major brand is putting its new lenses into mirrorless mounts, so that's where the future lens choice is. Old manual-focus lenses also adapt easily to mirrorless, which is a cheap way to experiment.

Check Your first camera for the reasoning, and Sensor sizes to see how crop factors change if you move between systems.
