I just checked. ~20% of the hot plate-only stoves with 4+ cooking fields from 2016 or newer consume 8KW+ according to a popular European price comparison site (these are certainly 3-phase). For induction it's about 10%. Almost all of them consume more than 4KW, so should be 2-phase minimum and obviously won't come with a Schuko plug.
