Single turbo stock ls3
IMO I would do a BW S475 with a T6 flange. The LS3 is a larger cube engine so the T6 will help reduce any issues with backpressure (not that you will have issues at that power). The Borg Warner turbos are VERY affordable and if later you wanted to crank it up a billet S480 would bolt right in its place. Ultimately it comes down to what you want to spend and what your end goal is, although it's always nice to have room to grow!
FWIW I run a standard S480 T6/1.32 on my stock LSX longblock with GREAT results

T4 on this mans Ls3 is fine
I've seen his setup and it works, no doubt T4 will definitely be fine on OP's setup. I just prefer lower backpressure if possible. I've seen T4's make 1100whp on V8's. With a larger cube engine it just makes the setup more efficient with the larger a/r IMO his car wouldn't suffer at all with the T6 over the T4 so that's why I recommended it. The only reason I would keep it a T4 setup is if it was a class limit.

376 isnt large enough IMHO especially with a small cam to need a t6
With the right converter a T6 car could footbrake very well also. My car actually footbrakes in the high 1.3's, I'm only running 12 lbs of boost and leaving on 7psi. I always use tbrake when track is good tho, but I think I could footbrake into a low 1.3 60' on a good track and ramping the boost in quicker.
I'm really not trying to argue though, we can agree to disagree lol : )
Either way good luck to the op and I'm sure it will be a blast when completed, LS3 is an awesome engine to throw boost at.
