5♣ is not exclusion as far as I know, exclusion requires a jump, for some people also a control rebid is possible, but a new suit without jump cannot be.
- Me and partner clearly agreed that 5C without jump was not exclusion. (we had the 2nd bidding)
- One player (sitting South with the 1st bidding) of another pair that plays the same 3D agreement as we, said that having 5C here should be Exclusion (I disagreed), or that it was very clear and obvious that 5C/5D exclusion would be the best agreement to have here (I started to doubt) and that partner should even take it as exclusion without having that agreement (I disagreed again).

Grand seems to be more easy to reach if the bidding starts with 1♠. Perhaps 3♦ is better overall, but since it puts me into unknown territory I have no clue how to reach using it. If you have better agreements over 3♦ perhaps its the best start. Having 4♣ as hearts and 4♦ as spades as a response sounds like a good start.
We have a very long (too long) system description without anything about follow-up after the 3-minor cue bid. So you are somehow right about the unknown territory. And maybe 1
♠ will make the bidding easier, but still I would prefer to show the Good 5-5 in a forcing way.
We would take 4C as a fit-bid for H or S and 4D as a good raise for H or S. If I would have had the decision then I would bid 4D here.

Anyway north shouldn't bid 4♠ IMO, his hand is really huge.
I agree.
