What it does
"Protection Fighting Style" isn't a real Magic: The Gathering keyword or ability. It sounds like a mashup of Magic's "protection" keyword and a Dungeons & Dragons fighting style, possibly confused because of the Adventures in the Forgotten Realms and Commander Legends: Battle for Baldur's Gate crossover sets.
The actual keyword is just protection, written as "protection from [quality]." It means the permanent can't be Damaged, Enchanted/Equipped, Blocked, or Targeted by anything matching that quality—remembered by the acronym DEBT. The nuance players miss: protection doesn't stop everything. It won't prevent sacrifice effects, "destroy" effects that don't target (like board wipes), or counters, and it doesn't remove already-attached auras—it makes them fall off as a state-based action.
In Commander, protection shines for slipping attackers past blockers and dodging targeted removal. If you saw "Protection Fighting Style" on a card, double-check the exact wording.
