When I was first presented the problem I just bid 5♣. But the hand has too many controls and a good fit so I was wondering what was the best route. Clearly 4♠ is the right call, the question then is, how should opener continue?

Six is on, but seven isn't. 4NT is KC? In what suit?
Good question.
I prefer 4NT to be RKCB rather than "Pick a minor.". Through "Pick a minor" has its advantage on some hands, like responder's 3-card
♦ and 1~2-card
♣. However playing 5-2 isn't a big disaster here so i'd stick to RKCB.
RKCB players would not change to play Simple Blackwood in this situation.
IF 4NT is RKCB, which i prefer to be.
Two options
1. Having mutual assumption of one suit , responder bid out the number according that assumed suit , opener then continue with 5NT or bid ?
♣, which would be to be corrected to ?
♦ by responder.
2. Apply "six card RCKB" then opener bid ?
♣, which would be to be corrected to ?
♦ by responder.
IF 4NT is NOT RKCB.
Responder pick a minor at the level of combined strength facing minimum 1
♣ 4
♦.
