If you are "considering conduit" and you actually need line voltage and low voltage, "consider" TWO conduits, one for low voltage/communications wiring and one for line voltage.
If all you need is to power access points, use POE and Cat5e or Cat 6a (either is fine for gigabit. 6a buys you some hope of 10 gig if you actually have hopes for that, but conduit means you can run the cheapest wire (5e) now and replace it if or when you exceed what it can do, easily. Which is the BEST reason to use conduit for network wiring.) Ignore Cat6 wothout the a, it's a waste of your time and money.
"Power line interference" is mostly a myth. Twisted pair communications cable is specifically designed to reject outside interference by its construction and the way signals are encoded/decoded. 50/60 Hz "noise" won't impact it at all. You'd have to have some incredible high frequency noise feeding into the power lines to have any effect on it. I know this because I do it for a living, and I have LOTS of network cables that make long runs near power cables due to crappy old buildings where there's no choice other than that, and I have switches that report error rates - which are pretty much always nil unless there's physical damage to a cable. Dang rodents - another reason to use conduit if you can.
I love fiber, but using fiber "inside your house to access points" will be prohibitively expensive (at the present time - in 10 years, you may be happy you have run conduit.) All my access points are connected by wires. Fibers (at present, for home-scale and even campus-scale use) are for between buildings, or a few special cases that are unlikely in a house.
As Harper mentions, "fiber optic" is not enough - it has to be a fully dielectric (non-conductive) cable construction , which is easy enough to come by, but there are fiber optic cables that have a conductive element (such as a tracer wire, or POE wires), and those are NOT acceptable in line voltage conduits. A line voltage conduit (with line voltage wires) is also what a fiber installer would consider a very hostile environment for a fiber cable, which is not happy about various forms of abuse such as sharp bends.
