It's really hard to find an elite defensive CF who isn't also a black hole at the plate. The ones who do are all 3.5+ win players. See Cedanne Rafaela, PCA, Andy Pages last season. A star example of this is Byron Buxton when he's not broken, Julio Rodriguez, Luis Robert before he crashed. These guys are extremely valuable.
Elite defensive CFs who can't hit are more common, but they're not quite as good. Victor Scott, Brendan Doyle, Kyle Isbel, Michael Harris, Denzel Clarke. None of these guys cracked 2 WAR last year, and they need to sustain best in the league type defense to even stick around in the MLB.
Myles Straw was out of the league in 2024 because his hitting was horrendous, and he projects for a 70 wRC+. You genuinely just can't live with that on a full-time basis from anyone whose name isn't Patrick Bailey and they're leaps and bounds the most valuable defender in the sport. Even Ke'Bryan Hayes who accumulated the fifth most defensive value last season, was only worth 1.4 WAR because of his putrid 65 wRC+.
