Feeder wire in and out of conduit


I am running a 60A subpanel out to my new garage. I dug a trench and laid 2" PVC conduit from the basement to the garage. The issue I am having is that the main service panel in the basement is in a finished room, and I can't run rigid conduit to it. I will have to snake the wires through a "soffit" to the panel. The soffit hides pipes for our kitchen sink, FYI.

What are my options? From what I have gathered, I can't run the standard 2-2-2-4 AL SER cable you can get at home depot because it isn't rated for direct burial. And I can't just use wires that are rated for direct bury loose in the soffit by the main service panel.

Is there feeder cable that is rated for both burial in a conduit and loose in the soffit? Or is there a flexible conduit that would be large enough for a feeder cable?

They make 2" flexible metal conduit. Or set a box and switch to SER.

They make cable rated for wet locations. I believe it is called USE, Underground Service Entrance. In Canada we call it NMW, Non Metallic Wet.
Or you could put a junction box the end of the conduit and join your cable to some THWN wires in the conduit to the garage.

The 2-2-2-4 AL SER is technically rated for wet locations, but the guy at Home Depot said it wasn't allowed in buried conduit because the ground wire is not individually encased in plastic, just paper.
