What would be the best possible way to put a sub panel in a detached garage. All wiring will be in 1 1/2" PVC. Ground at gargage. I know no service cable buried in conduit. Should i J-box and change over. It has been along time since I have done one. Thanks.

I would just do the PVC stubbed up, wall to wall, LB through the walls and you only end up with 2 90s so pulling is easy. Pull in 4 appropriately sized THHN/THWN and be happy.
With 4 you are not regrounding the neutral at the garage. Drive a rod and ground the garage EGC bus.

If I run service cable to a j-box and change to THHN that would be acceptable.

They still may want it sleeved where it comes out of the ground and up the wall. Whether something is subject to "Physical damage" seems to be a local thing.
