If I follow D, can I get the card details only and then charge in the server? How easy is it to do? Are there some docs or examples around?

For D yes: https://stripe.com/docs/payments/save-and-reuse?platform=checkout for Checkout and https://stripe.com/docs/payments/save-and-reuse?platform=web for Payment Element, just similar to A and C

I want to redirect the customer to pay in stripe checkout but I don't want to create a product and price for the booking because I think is unnecessary and wrong design. Can I create a stripe checkout session for a payment intent?
Creating Checkout Session alone is ok, and you can create the produce and price data on-the-fly

Is there a better approach I have not think about?
Generally that's all I can also think of
What is the best way to handle unpaid bookings? Should I use the same payment intent?
It will be incomplete PaymentIntent on your Dashboard. You can just ignore it or query its number for analytic if you want

I need to protect the property of last-minute cancellations. How do I handle this? Can I get/ store the card details somewhere and charge the customer if he wants to cancel last minute?
Yes possible with 2 suggestions in the D flow above, or you can also use the Separate Auth and Capture flow, which gives you maximum of 7 days in most cases for not charging the customer
