I don’t want to wake up a stranger in a strange world.

That already happens to everyone. We call it "birth."

If revived, I wouldn’t have any useful skills.

People make a living now with allegedly primitive skills. I live in rural Arizona, and I know guys who work as cowboys and ranch hands. One of them told me the other day that he had to round up and brand some steers.

The people who revive me might torture me.

Or try to rape you, like in the "reverse cryonics" time travel story Outlander. Claire seems to manage regardless.

It’s selfish of me to have more than my fair share of life, especially since the world is overpopulated.

People in a post-transition world might have a quite different value system regarding this "fair share" notion. "This guy in cryo lived only 77 years? Wow, he died young. Give him priority for revival and rejuvenation."

I believe in God, the real one with a capital G, not an extremely smart artificial intelligence. I don’t want to postpone joining him in the afterlife.

God calls you home according to his schedule, not yours. If you survive to a future era via cryotransport, God obviously hasn't called your number in the going-to-heaven queue yet. Wait your turn like everyone else, even if you have to wait for centuries. Paraphrasing Luke 19:13, Jesus tells his servants to occupy themselves until he comes for them to account for their service to him.
