Dammnnnnn you'll get every recommended product under the sun haha so many options fit this criteria.
I don't think anything natty will completely mitigate the loss of strength and/ or some mass you gained. Definitely keep Calories up during PCT, and aim to stay in a mild 'bulk' to keep protein synthesis high.
As for products, Xgels and ylur SERM of choice would be a good combo. Maybe even Anabeta Elite or Massmax XT.
So many options. But first and foremost keep Calories up
