Favorite???
There’s so many that would work well.
I like the 30-06 basic case, so 25-06 to 35 Whelen.
But a 257 Weatherby l through 358 Norma Mag work.
On a 57 mm case most will work 6mm Rem, 357 Roberts, 6.5x57, 7x57 and maybe 7.92x57
6.5x55 & 260 & 6.5 Creedmoor & the 243
On a 308 case I’d pick 7mm-08 or 308.
My personal favorites include 270, 280, 280AI, 30-06 & 7mm RM.
But the 270 Weatherby might be a nice choice and is pretty flat shooting.
