First of all, just curious but are you the same COILBOOK, from the kids YOUTUBE channel with max the train ?
You do great work. Impressed.
Second on this scene, I think you need to rethink the scene a bit. Whilst Path tracing is amazing, its slow and struggles in a nightmare scene like this with high complexity and low low lighting. Direct + AO is incredibly good at certain things at certain times. Here are some thoughts
1) You can blend the two separate passes together, and mix the best of DIRECT for a little lighting fill, with the best of PATH. You don't have to treat them as totally seperate. I often mix two passes together to get the best of both.
2) If you are worried about noise and time, you certainly don't want to increase the passes or the glossy etc numbers. I would personally run a really strong PATH pass with just "2" diffuse depth to get really dramatic lighting and make it render fast and clean. Then mix that with a general ambient pass like a DIRECT pass.
3) You are going to have to cheat somewhere. Everyone does. If you are trying to light that huge scene with just those tiny lights there is no way. You can keep those on for just "effect" to look good, but then have some much bigger, softer "invisible" lights actually doing the hard work. So for every one of those small lights, copy it but make the radius 10 times as big and hide it. That will give a lot more light, but soft and easily rendered.
Finally ANY render engine will struggle with this. Don't switch from OCTANE. It is the best one out there. If OCTANE can't do it, nothing can better.
