Given an auction like say 1♣ (strong; artificial) - (1♥) (natural) - 1N (GF with stopper), it seems like opener's rebids should be natural, with the cue-bid (2♥) probably reserved for Stayman or something along those lines.

Note that in the case of artificial overcalls (say if their 1♥ showed ♥ OR 2-other suits), using the cue for Stayman likely doesn't make sense. One possibility is to use 2♣ as Stayman, and show single suited ♣ hands with 2♠, but it consumes a lot of space (especially if the overcall is at the 2-level and responder bid 2N to show the balanced GF).

Do the folks on the forum have any special agreements regarding the above?

In a strong club system: 1♣ (1♥) ?

We use Roy Hughes recommendations:

Pass 0-4 hcp
X 5-7 hcp Balanced or 4+♠, Not GF
1♠ Transfer to 1NT with ♥ stopper, GI
1NT Transfer with 5+♣, GF
2♣ Transfer with 5+♦, GF
2♦ 4=1=4=4, GI+
2♥ Transfer 5+♠, GF
2♠ Transfer to 2NT w ♥ stopper, GF
2NT 5-5 Non-Touching suits (♣ + ♥ / ♦ + ♠), GF
3♣ 5-5 Minors, GF
3♦ 5-5 Red Suits, GF
3♥ 5-5 Majors, GF
