Does it work with Sony teleconverters?

Yes, it accepts Sony's 1.4x and 2x E-mount teleconverters, extending reach to 840mm and 1200mm with some loss of light and sharpness.

Is it good for handheld wildlife shooting?

Yes. Optical Steady Shot and the internal zoom help, but the weight means most shooters use a monopod or gimbal for long sessions.

The 200-600mm gives much more reach and costs less, while the 100-400mm GM is smaller, lighter and brighter but shorter.

At f/5.6-6.3 it needs good light; indoor or dusk action often requires higher ISO or a brighter prime.

It is a full-frame Sony E-mount lens and also fits APS-C E-mount bodies, where it gives a 300-900mm equivalent field of view.
