Welcome to the forum

First, I want to tell you thank you for being responsible and researching about parrots before getting one

In this situation you can make the best possible choice from the information you get regarding your lifestyle for what parrot you should get. I congratulate you.
Given the time and effort willing to put towards the bird/s will have an outcome of the birds behavior and screaming. As far as the species best suited towards you work schedule is, i have no idea, so listening to pajarita and wolf would be a good idea.
My adoptee came with no forging or shredding toys, and at a year old, this was unacceptable, in my opinion. Bordem is another reason for their screaming - during his month here, I have given him some more forging toys, which helps stops the bordem, which helps stop the screaming. The 'honeymoon' phaze lased till about a week ago, and in that week, there were two days where he was being a bit crabby and noisy (earsplitting screeches every five seconds - be ready for that no matter what parrot you get). Giving them new things to do will help - they don't have to be costly, but exercising his brain often with new stimulation (or with toys/things he hasn't seen or played with for a while) will keep him quieter.
My boy is an eclectus, and they are known to be 'quiet' birds, but still can scream quite loudly. Coming home from work yesterday i'd bought a shredder/foraging toy, put some nuts into it, which kept him entertained, and he had a shower this morning - barely made a peep.
The one piece of advise when getting a parrot is - research, research, research, don't get on impulse, in store parrots can be very different then being at home with you alone and in a new environment. Figure out what species is best, then look around for that species.

Also diet is a crucial thing. Each species has different needs. Julian, being an eclectus is on %80 fresh fruit and veg, and no pellets. if you get a bird with difficult dietary requirements, make sure you are able to provide this for them.
