Re: Do I want FFP, or SFP?

First, SFP or FFP. If you are doing any ranging with different powers, FFP is faster.
But, that depends on your reticle. I prefer moa, but mil is easier to translate into both metric and imperial. No matter what, get the knob adjustment to match the reticle.
The reason I say to get a reticle you like is with FFP your reticle is fixed in relation to the target. As you range with the reticle, you never have to worry about being at the wrong setting so that your reticle doesn't match the values it gives. On an SFP scope, you have to be at a given power for the values of your reticle to be true. Either way, a reticle is more useable when you have go to values for it, rather than stop what you are doing and have to work up some math. Having to do that is almost useless if trying to figure a target on the move toward, or away from you. In that scenario, you estimate, see the miss/hit and hold. A reticle with enough values to give you the ability to adjust is nice. Having too much clutter in a reticle is not. For that reason I don't like Horus type scopes. Learning to plumb up and slide a mil or moa type standard crosshair is the way to go, IMO.
Now, shooting within your scopes travel, meaning both the knob adjustment and what you can hold on the reticle, is best served with an FFP scope. However, if you go beyond this range, dialing down to a known value on an SFP will give you extended range. Meaning a true one mil value at 15x is a two mil value at 7.5x. This is not standardized between different scopes. So you should check it if you do. Using this method I was able to accurately hit at one mile using my 12-42x56 2FP NF scope. But, I did sell it, as it didn't have enough travel.
Sticking to to the 16x-24x range of top power on a scope will usually give you plenty of travel for 1k. With a canted base you can increase range potential.
