You don't buy a wok like a Chinese restaurant uses because you can't use a round-bottom wok on an induction hob.
You can buy induction hobs specifically for woks, but they're a bit specialist, as are those colossal burners in the picture above.
Generally speaking, for a wok you want as much of it heated as possible. Induction [or any electric hob] will only ever heat the flat surface in contact with the ring. Domestic gas is better, & you can tilt the wok to aid ingredient distribution rather than having to leave it flat on the ring all the time.
Home-cooked Chinese-style food must necessarily adopt a different technique because you simply cannot generate the same amount of heat as a commercial kitchen.
If you don't have time/skill/patience to season a wok & keep it seasoned, then get a non-stick. Just don't get a cheap one, or it will peel off in three months.
My own wok is one of these - Masterclass - and has withstood everything I can throw at it for over two years, without showing any sign of scratching, burning, evaporating or anything else detrimental to the surface. I treat it with little respect, though I only use wooden or plastic utensils for all my pans, & wash it in regular washing-up liquid (dish soap) with the same brush I use for everything else. The outside is scuffed & scratched, but the inside still looks as new.
And it only cost 30 quid [bucks/euros].
When you're throwing food around in this, you will quickly realise why you don't want a cast iron one… the weight.
