Can you feed a 100 amp sub panel with a 50 amp breaker?

It’s the same with subpanels: The “100A” is a maximum rating. Do not exceed 100A. However, you certainly should exceed your feed-breaker size of 50A. Even if 50A panels existed, they would be very small in terms of numbers of spaces.

Is 100 amp panel enough for a shop?

As an Electrician by trade, A 100 amp panel should be plenty. You can get one with 20 or 30 slots. If your shop is 1,000 square feet or more I would recommend a panel with 30 slots, otherwise, 20 would be fine.
