Opener's rebid with 544 hands

[EricK]

Is there a standard approach to which 4 card suit opener should rebid on various 544 hands on the second round if responder bids the void or 1NT?

 

There are a few different situations:

eg with 5♠ 4♥ and 4♣ after 1♠ 1NT, is it normal to rebid 2♥ (because majors are more important) or 2♣ (to leave maximum room for responder to bid)?

Is the answer essentially the same with 5♠ 4♥ and 4♦ after 1♠ 1NT? What about if the response is 2♣?

 

Or with 5♥ 4♦ and 4♣ is it normal to rebid 2♣ or 2♦? Does it matter if the response is 1♠ or 1NT? Presumably the answer is the same with 5♠ instead of 5♥.

 

And what about 5♠ 4♦ 4♣ after 1♠ 2♥ where there is much less room? Of course here there might be the option of repeating the ♠.

 

And then there's 4♠ 4♥ 5♦ after 1♦ 2♣ Again rebidding 2♦ might be possible allowing responder to bid his 4 card major (but what if responder is 4405 - what is his standard 2nd round choice?).
