It is interesting about the hooks. Hooks have a lot of variables, how heavy the wire is, the shaft length, the size of the gap, the material, etc. A size 2 Gamakatsu SC-15 looks tiny and fragile next to a Size 2 Mustad C70SD big game light.
I tie mostly on size 2 and 4 hooks for general marsh and secondary bay fish or size 1 or 2 hooks for unweighted baitfish patterns. I’ve got a few 1/0 baitfish.
In general, as compared to fishing plugs and conventional jig heads with much beefier hooks, fly hooks do just as well or better in getting good sets and fish to hand as the bigger trebled hook plugs and or jig heads.
A lot of fish are hooked right in the corner of the mouth.
Sometimes, it’s more toward the nose
Once in a while, they get it a little deeper.
