You have pretty much my measurements and I went medium (54cm) with my RT-58. That said my KTM is a 57cm, but I fitted a 10mm shorter stem and they feel pretty much the same when seated. Given the OPs dimensions, Medium P-X is the way to go. It's always easier to stretch a bike than it is to make it smaller, after all.This is why you should try for size everybody is different, when i bought my PX I tried a medium & a large,after a lot of delibaration I went large, although it was a nice ride I think I should have gone medium, I think the compact design makes them look small, I am 5ft 10" 32" inside leg and ride a 54" in most bikes, the shorter top tube length of the medium 54.7cm would have suited me more than the 57cm of the large, I am not a big fan of compact frames.
The OP said short legs and short reach, thats why I recommended medium.
I couldn't argue with that as we both know Rival 22 is pretty damn slick. Even with Di2 in the house, I don't find myself missing it (too much!) when the RT-58 and it's mudguards are called upon. I still prefer the look over the jelly-mold Shimano, regardless of how good the Ultegra Di2 is.PX pro carbon is £750 this weekend with SRAM rival can specify stem length, crank length, handlebar width

On a more general note; why shouldn't the OP spend £1k on a first bike? I'd have bloody well blown that, if I'd have it at the time. I got similar comments when I asked advice on a £3k n+1 and all of the dissenters were wrong, full stop. I am in no way what-so-ever suffering what-if? syndrome.
As regards 105/Rival/11-spd, well I'd consider that worth it too. Being able to get a 32* tooth granny gear on the rear is dead handy early on and it also means you don't suffer big jumps between the other ratios. Fact is, 105/Rival (complete) is easily available on some really decent £1k bikes and if you can have it, you should, because it's just nicer to use. When I started back in the '80s, I looked in awe at 12-spd bikes, but managed fine with 10-spd (8 actually usable) but would I go back, or say that's all you need because that's all I've got? No. Knock yourself out!
That's my 2p.
