For "fun" I looked up every season in MLB with a strikeout rate above 40% and over 150 plate appearances. Unsurprisingly, each of the 15 such seasons have come in the last 10 years (Javy Baez was the first in 2014 - 229 PA at 41.5%). Only 4 seasons had an above average production by wRC+.
2021 Patrick Wisdom - 375 PA, 40.8 K%, 117 wRC+ (.823 OPS)
2022 Keston Hiura - 266 PA, 41.7 K%, 115 wRC+ (.765 OPS)
2023 Joey Gallo - 332 PA, 42.8 K%, 103 wRC+ (.741 OPS)
2020 Miguel Sano - 205 PA, 43.9 K%, 101 wRC+ (.757 OPS)
