OP is playing Acol.

If 3H is forcing (the game seems to me to be tough enough without having to jump everytime one has any extras), the 4H was an error.
An easier hand if playing 2/1 I agree.

I would open, but would respond 1NT with the North hand.
No, 1NT shows 6-9 in Acol. Partner will never believe that we have a strong 10-count with three-card support and a good five-card holding in the other major!

I would prefer to make a simple rebid of 2S which is always a one round forcing bid. […] It is best in my personal opinion to show SIX carded spades worthwhile and more so if one is playing ACOL.
No, a 2 spade rebid is not forcing in standard Acol. Partner will often bid again but there is no obligation.
No, a 2 spade rebid does not promise a six-card suit in Acol – imagine a minimum hand with 5 spades and 4 diamonds (5242 maybe) – There is no other bid than 2 spades.

Wanting to bid game is reasonable, but I don't think I've ever had only 3 hearts for a 4♥ bid here.
I have. With five spades and four hearts, I will often have a splinter available and since partner has guaranteed a five-card heart suit I would expect this 1S-2H-4H auction to show a three-card holding much of the time. The auction does consume a lot of space but it has conveyed some inferences about the hand: strong enough to play in game opposite a 10-count, but not strong enough to bid a forcing 2NT followed by 4H or 4S. So, would I ace-ask after this sequence? I’m not sure …

Analyzing hands by looking at the lie of the cards, and concluding that the winning line is the correct line is a very good way of becoming or remaining a bad bridge player😊
This is the wisest thing that has been said so far in this thread. I find it very difficult to comment objectively on what I would have done when I can see all four hands.
