I think either cartridge would be just fine. The 30-06 earned its reputation long ago, when loads for it were about like 308 loads today. As a rule, there’s about 100 fps difference between the 308 and the 30-06. That said, I've seen velocities with factory loads with the same bullet weight vary by as much 150 fps, so a fast 308 might outrun a slow 30-06. The 30-06 has a slight edge with bullets 180 grains and up, but 150-165-grain bullets are so good these days that you probably don’t need 180’s.
Factory ammo for both cartridges is superb, but the 30-06 tends to offer bit more choice if you have to buy what’s on the shelves in a specific store. You can get pretty much anything for either of them online.
With what you said about how you use this rifle, I’d upgrade to a better 30-06 barrel and glass bed the rifle, then spend some time chronographing loads and working up a drop chart.
