I think you should have no problem learning either technique. Decide which divisions you prefer, and train from there. Would you rather trick out the gun with a mag well, etc? Does your state allow high cap mags for Ltd? If so, train to disengage the safety and run it SAO. Would you prefer keeping it "stock" from CZC and stock mags? Then learn the DA first pull. You'll also need to dry fire practice manually lowering the hammer after LAMR for the DA start.
Either way, dry fire is your friend. Whichever you decide, it doesn't require a single live-fire round to get it nailed down.
The good thing about the 75, is that is very versatile and you could run it either way. The downside to running it in Ltd would be scoring minor if it's 9mm.
I just switched to an SP01 Shadow from Mink. I came from an M&P 9 Pro with magwell in ESP/Ltd. I now shoot SSP/Prod. I won't shoot Ltd Minor again. The triggers on these things are so good, the DA first pull isn't very difficult to learn.
Again, dry fire is where you need to learn all of this stuff. Sure, go shoot the thing since its your new toy, but dry fire is where you should be ingraining the technique that you choose.
