I use a combination of things on my birds, they are very tame and have never been very hard to convince that they should go in their cages though.
We bought them the biggest cages we could fit in the house

Nila had a decent sized cage already, but he loves his new cage and goes in there to play and nap all the time.
We set up lots of foraging toys when we are planning to leave them in the cages. They typically get vegetables on a skewer, and various puzzle toys loaded with pellets, a bit of seed and a small piece of fruit or berry. They like finding their treats so they are usually in the cages before we have even finished packing all the toys in.
They both have certain favourite foraging toys that are associated with high value treats, so if Sapphire sees us playing with a pill box she zooms straight over.
Shreddible toys, foot toys and browse. I sometimes jam a couple sunflower seeds into the yucca toys to stimulate their interest.
We also will put them in their cages for a treat and leave the door open so they don't associate being put in the cage with being locked away. When they are locked away, they are still given attention and treats when they are behaving appropriately.
They go to their cages about half an hour before bedtime to eat some vegetables before bed. It's now a habit and they fly over to me or say our names over and over until we get their om noms ready. They also get a couple treats just before their cages get covered.
All that stuff works for our munchkins, I hope some of it might be useful for your guy.
