Ah. I try to do the card creation while I'm taking the notes in the first place. I'm not sophisticated with clozed yet, just Front/Back for Anki right now. That works well both for org-anki and for polar bookshelf.

Readwise lets me make an annotation clozed while reviewing it, which is nice. It auto-converts highlights into questions.

I'm experimenting with different card types in org-anki, using yasnippets. That's a nice workflow. I need to look into auto-collapsing them after I'm done editing them.
