I have a pair of APC New Cures and Petit Standards. The latter are an awesome fit. Skinny without being skin tight or too hipster: a great slim cut.
I think, as you suggest, the Petit New Standards would be better as they are more roomy in the thighs. I'd be tempted to get a pair of those next just to complete the trilogy of slim-APC cuts.
I can't recommend the APC's enough. The denim quality is 10X better than the Nudie's I owned for a week, the cut is sublime and the detailing is nice and minimal. They fade really nicely too.
If you can pick up a new pair off eBay for £80 or less you will be laughing. Just don't get them too tight in the crotch or you will risk a blowout if you abuse them too much (unfortunately my New Cures are dangerously close after 7 months and one soak/wash).
