Bid cap
A bid strategy that sets the maximum Meta may bid in any single auction.
It gives you the most control over price and the least over volume: if the auctions you need cost more than the cap, the ad set spends little or nothing.
Set it from real data, and loosen it if the ad set underspends.
Where to find it: Ad set (or campaign) settings, Bid strategy.
