Mine is pretty much the same age, never a great sleeper, but from 7 months on we started co sleeping. It was the only way for any of us to get any sleep at all, and it was clearly what he needed. They're wired to need safety and connection and that was the game changer for us. By that point I'd worked 50 hour weeks for 3 months on an hours sleep each night.
Fast forward two years, and he starts the night in in own bed, he's been in a proper single bed since he could walk and climb at 10 months- but he never ever slept more than an hour in a cot before then. He wanders into ours halfway through the night. Most nights he then sleeps the rest of the night. The 2 weeks after we moved house were hideous though, he just felt really unsettled and probably frightened at night.
Sounds like co sleeping doesn't work for you, but could you try a mattress for him on your floor? Or you sleep on his floor for a while? It sounds like he felt safe in his cot, so maybe you could mimic some of that security by having a semi enclosed bed? There's loads of ideas online for that sort of thing. Would an ikea bed tent thingy give the same feeling possibly?
Might be a bit controversial but mine falls asleep next to us on the sofa after a book etc, we tell him it's sleep time and we quietly watch TV as he falls asleep and then we carry him to bed when he's fast asleep. It's just our routine and it works for us. I think the noise is reassuring for him.
I know people say you create a rod for your back, but I hope and believe that once they understand that you'll always be there at night if they need you, eventually they'll feel safe and secure enough to sleep alone. It could just be a case of insecurity as you've recently moved. I don't think it's about boundaries, control, pushing buttons or manipulation.
Good luck, it'll all pass with time and in these moments do whatever it is you and he need to do to both get some sleep. That's the most important thing.
