Generally if it is safe for a human infant, it's safe for a bird, provided it's not filled with anything harmful like the rattles and keys that you can freeze or anything that can be easily swallowed. I've been searching for plain baby keys since I got my conure but I just can't seem to find them anywhere!
For specifically bird toys, I suggest shreddable toys, my conure and I've noticed birds in general are feathers of mass destruction when it comes to something that can give under a bored beak! Lucy has 3 shredder toys hanging in her cage right now along with some gardenia branches with the leaves still on them

Be careful with rope toys, I have one in Lucy's cage and one in Bleu's as well, but I always check them for frays, loops, and anything that can be potentially harmful. There's many horror stories on here about birds hanging themselves on loose loops

I think a cuttle bone is optional with conures

Just for reference, in case your baby isn't a fan of it (my conure wasn't a fan of hers, but some of her siblings love them lol)
Two sets of dishes is great! I love having a secondary set to swap out when I just don't have the time in between classes to do all the dishes and feed the birds!
Congrats on your new baby! I've come to learn there's nothing quite like a bird for a companion <3 My fids have filled the void I've felt for a long time

Smarter than a dog, cuddlier than a cat, and just as much, if not more personality than most people I know
