Boy name please

I am extremely bad at making decisions. This is harder than I thought. So please be patient with me.

So here are the names.

Charles, Henry, Edward, Conrad, Cassian, Dashiell. We have agreed on the list.

Conrad? I really like it right now. What do you guys think. And for French speakers. He will be going to a French school. Is he going to be laughed at? “Con” (un con). Or even in English “Con”. Or I am overthinking.

Dashiell, my husband says nickname Dash is not good. ?

Cassian?

I wanted strong and distinguished name. Uncommon but nice.

Thank you for your patience
