I was the only one to bid 3♠ (forcing), which means it's probably a poor call. However, I don't understand why. The hand seemed suitable for play in spades if partner can product Jx or xxx, and at worst we end up on the 4-level with a 9-card fit. So, which considerations am I missing and/or placing too much value in?

You can expect partner to cover at least 1 ♦ loser. My pre-empts tend not to have much in the other suits. Also, if partner doesn't have ♠J you're quite likely to have 2 ♠ losers. So it looks like an easy pass to me.

I don't expect to make 4♠, but I also don't expect to beat 4♥, and I would rather bid now than hope 3♦ gets passed out (doesn't seem so likely), or guess what to do over 4♥.

Maybe we have 2 ♣, a ♦ and a ♠ in defence of 4♥. Also, I'm not sure LHO is that likely to act, we have a lot of the HCP.

An ace more (maybe even a king) and it's an obvious 3S bid.

What do you make in diamonds? In spades? And your 3♠ bid is forcing.
Yes, the opps MAY make 9 or 10 tricks in hearts. But will they bid over 3♦? Far from clear. And if you bid over 3♦, you may wind up in 4♦ or 4♠, possibly doubled.
You don't have a 3♠ call over 3♦. And it would not surprise me in the least that a 3♠ call led to a bad result.
Let partner's preempt work. Maybe they won't find their heart contract.

I'm not sure I agree with the hand you gave, though. I can reasonably expect that with 10 hearts and 23 HCP between them, the opponents will find some action over 3♦, can't I? Moreover, with seven spades missing, isn't partner entitled to his share of them?

Let's assume partner has 7 diamonds and opps have 4. This leaves partner with 6 spaces and opps with 22.
Probability for 0 spades with partner: (22*21*20*19*18*17*16)/(28*27*26*25*24*23*22) = 14.4%
Probability for 1 spade with partner: 7*(6*22*21*20*19*18*17)/(28*27*26*25*24*23*22) = 37.8%
Probability for 2 spades with partner: 21*(6*5*22*21*20*19*18)/(28*27*26*25*24*23*22) = 33.4%
Probability for 3 spades with partner: 35*(6*5*4*22*21*20*19)/(28*27*26*25*24*23*22) = 12.4%
Probability for 4 spades with partner: 35*(6*5*4*3*22*21*20)/(28*27*26*25*24*23*22) = 2.0%
Probability for 5 spades with partner: 21*(6*5*4*3*2*22*21)/(28*27*26*25*24*23*22) = 0.1%
Probability for 6 spades with partner: 7*(6*5*4*3*2*1*22)/(28*27*26*25*24*23*22) = 0.002%
=> Average spades partner is entitled to: 1.5

The misnomer "preempting over a preempt" normally applies to an opponent acting with weak values over a weak bid.

1. You might make 4♠. Not particularly likely, but its within the realm of reason.
2. More importantly, an auction that starts [preempt] - (pass) - [new suit] is notoriously difficult to defend against.

We may not get to play in 4♠, partner could be forced to bid 4♦. Making a forcing bid on this hand seems wrong.

Edit: sorry I mistakenly thought 3♦ was an opponents call. so 3♠ is forcing and IMO a correct call assuming ♦ tolerance or extra values
