As stated above, this depends a LOT on your circumstance. Large parrots are a huge commitment and definitely a challenge-- almost all species are needy, attention-craving, and EXTREMELY messy, expensive, and time-consuming to own... not to mention how long-lived they are. You'll be giving up a TON of time, money, and energy on this bird, and if you can't provide that, then you might want to reconsider because parrots (especially bigger ones) are usually a very challenging undertaking.
With that said, here's my experience with the medium-to-large species I've owned:
AMAZON: I currently own two amazons, and they are delightful but also incredibly challenging to keep up with. I've noticed that zons tend to be portrayed as super intelligent and silly, especially on social media-- and while they are VERY smart and fun, they're also noisy. SO noisy. And loud. Mine spend most of the day screaming, although I would imagine this is down to the individual bird.
They are also incredibly destructive, and, unfortunately, there's nothing you can do about it, because chewing is a natural parrot behavior. My YNA chewed up my sofa, table, chairs, bed frame, walls, floors, and everything else in my home, and I've spent thousands of dollars on repairing the things he's destroyed.
I am currently in a pretty great position in terms of bird ownership, because I work from home and hardly ever go out. This means my birds spent all day out of their cages, playing with toys and hanging out with me while I work on the computer. It's been like this for years, and I'm unsure as to whether I would have gotten an amazon if I worked a normal 9-5 job because of how much attention they demand.
They are individuals, however. My amazons, while both loud and needy, are polar opposites in several regards. You never know what you're getting into with these guys. Keep that in mind while considering this.
PIONUS: I adopted a bronze-winged pionus a decade ago. He was a rescue with an incredibly traumatic past-- it took me 3 months just to get him out of the (tiny) cage that I got him in, and he never really came to trust me. This means I'm not entirely familiar with the personality of an "average" pi, but my bird was, while extremely timid, a pretty gentle and playful little dude (especially towards the end of his life). I've done a lot of research on pionus and most owners describe them as relatively laid-back and gentle.
CAIQUE: Owning a caique was, for me, a mixture of pure joy and absolute hell-on-earth. She was so quirky and silly and loved to bounce around, roll on her back, carry random objects all around the house, etc. There's never a dull moment with a caique. They are, however, VERY difficult to keep up with, and their personalities are so incredibly active and clownish to the point where it often became overwhelming trying to give her the attention she needed. It also didn't help that I was in college during that time and often went completely sleepless trying to balance homework and caique motherhood.
Looking back, I probably wouldn't do that again. Adopting a caique was a very impulsive move on my part. If you work a typical 9-5 job, I honestly wouldn't recommend one at all, because they crave attention 24/7 and there's really no break from them. It was really hard to come home, exhausted after a long day, and then have to entertain a hyperactive, mischievous bird. Still, caiques are delightful, and I'm glad to have experienced the joy of loving one.
Also, caiques bite very frequently and hard. I don't recall ever having a bandaid-free hand when I had mine lol. A lot of the time, it wasn't her trying to be aggressive- they're just hilarious little birds who bite to let you know how amazingly hilarious they are. Bites are, obviously, just a part of owning any parrot, but for such a small bird, my caique's bites were pretty painful and could draw a lot of blood.
