Reddit reviews 100ft Cat6 Outdoor Waterproof Ethernet Cable Direct Burial (600MHz) Shielded (Pure Copper)

Buy direct burial CAT6:

The specifications for Ethernet is 90 meters (295ft)max. (https://en.wikipedia.org/wiki/Category_6_cable#Maximum_length)
This gives room for 5 meters on either end to connect the plugs on the wall to the plugs on the destination. If you're running it underground, get yourself some cable rated for direct burial, like this: http://amzn.com/B002HFEBYM <-- That would get you 100 feet of gigabit Ethernet underground and outside. That's 1000mbps. Happy day. You're good.
Just to be safe, and because it's so cheap, you might get some PVC conduit and run it in that, just to make sure that it doesn't accidentally get sliced.

Im also wondering if it was the cat5 since I am using PoE. I’ll have to acquire STP type cable to reduce noise.

Something like this?

Also, I dunno the physical situation you're dealing with, but these are preterminated cables. Assuming you can fit the head through the walls to get wherever you need them, you could just do that...

Yes if you plan to run a cable outdoors at all you must have a surge protector on it or risk damaging your equipment.

Unless you’re wanting 10Gbps or more, Cat7 is pretty pointless. However, some exterior Cat6 could be cheaper and more durable (although that cable you link to is really cheap). There is plenty of exterior-grade cable floating around, but if you want pre-wired ethernet connector, Amazon has a few options, like this one:
https://www.amazon.com/Outdoor-Waterproof-Ethernet-Direct-Shielded/dp/B002HFEBYM which is actually more expensive than the “Cat7” you link to above (I put that in “” because knowing the Cat7 specs, that cable looks like it wouldn’t meet them...however, looks can be deceiving).

I’ve done a number of exterior ethernet cabling jobs and provided the cable is rated for exterior use it should do the job. When runing the cable try avoid proximity to AC power, high-current switching (AC units, electric hot water systems etc) and try find somewhere out of the sun (UV kills the shielding regardless of how it is rated). The heat/cold wont be a big problem unless we’re talking arctic-low or Sahara-high temps. Also, avoid sharp bends etc; most Cat5/6 is supposed to be run with minimum 20cm/8in bend radius. Cat7 is usually much stiffer (and requires earthing the insulator too) and has a minimum bend radius of 30cm/12in (IIRC). Securing the cable should be done with exterior-quality fasteners which wont pinch or crash the cable; don’t make the fasteners too tight or is will pinch in cold weather.

My main concern with that Cat7 you linked to is that it is bent up like a pretzel and that is REALLY bad for Cat7. In fact “real” Cat7 would be completely ruined bending it like that. From my experience, it looks a little “too good” to be true. A 100ft Cat6 exterior cable pre-terminated with RJ45s, should go for about USD$0.50-0.75 per foot for a good quality commercial cable. If you buy a roll of Cat6 exterior cable and some RJ45 crimps, you can drive the $$/ft down, but you’ll end up with a LOT of left-over cable. Most rolls start at 800-1000ft. Last of all, if you run a conduit, you can use plain-old interior cable. Same rules for routing around AC lines etc, but might be cheaper.
