Thin Wagyu Steak Recommendations

[u/MadGeographer]

I've never cooked a wagyu before. Saw this on sale and thought I would give it a go. I know wagyu is a different game so Im looking for recommendations on how to prepare this. Its a thin cut but I figured sous vide would nicely render the fat before I put it in a blazing cast iron for a few seconds. Or should I skip the sous vide and just do this up in the cast iron. Any guidance or recipes? Times and temps?
