Hello, welcome to the forum.
Its never to late to make friends with your burd. I'm sure you have seen news stories of people who have gained the trust of wild bird's and have them eat food out of their hands. Time and patience.
On toys. Those pipe cleaners aren't safe. The metal in them isn't safe for birds. You can use just plastic straws, a cup of plastic bottle caps with some seeds sprinkle in the cup. Cut up a brown paper bag into thin strips, and make like a pom pom. I have those for my burds and they like them. My freind has a cockatiel and his loves to chew popsicle sticks . Also his loves to chew playing cards. He just weaves one from the deck of cards thru the cage bars, they make a little pop when he chews them that he seems to love. I DIY toys all the time for my birds. Oh and those Chinese finger traps are fun for them to chew.
My friend's cockatiel loves to sit on his arm or shoulder or head lol. But his doesn't like to be petted. He whistles, chirps and so adorable, looks just like yours!!
Now because I'm a momma hen I always talk veggies. Never try and force them to eat veggies , just add a couple of veggies as a free choice in addition to what you feed. For leafy greens like Swiss chard or romaine lettuce I find hanging helps them getting nibbles from your burd. You csn use a new clean shoe lace and punch a hole on lettuce and hang up, or just weave a leaf through the bars. Lettuces like romaine actually have good nutrition and vitamins!! Also bell peppers with seeds, or red hot chili peppers are well liked by most parrots and high in beta carotene needed for vitamin A, I offer in shallow wide bowls, parrots seem to try them better dread out do they can see them. Broccoli. Carrots, green beans, peas, corn all fresh are great to try too. Never give up of things aren't tried or are rejected. It can take months of them seeing them before they try them. All of my birds love their veggies. Its also a great enrichment for them, and like a chew toy for them . I offered mine an artichoke with leaf spines cut off, they loved chewing it up!!! Loved it, but didn't eat it lol.
Anyway people think birds don't like veggies, but they love and crave them!!! Its just st furst they dont recognize them as food, and didn't have parents and flock showing them veggies when they were young. So dont give up, they are so good for them, and fun for them!!

It took me 2 months to make freinds with my fearful burd. So it can take time, and move at a burds slow pace. But so worth it! Cockatiels are so funny cute and smart.
