Network cabling for BlueSounds' Node 2i Network server


I plan to purchase a Node 2i later this week.  
Question regarding ethernet cabling: What quality and bandwidth capacity would you recommend for connecting the Node 2i to my Fios Router? My router is in my den on the second floor, while my stereo system is in the basement. I just plan to drill a opening in my drywall and run the ethernet cabling (about 50 ft.) to the Node 2i in the basement.
 Here were some of the types cabling I've looked at below. It seems the higher the numerical number, the more the bandwidth:
Cat 6, Cat 7, and RJ45 High Speed Internet network cable.  
Obviously, I want to purchase the cabling that provides the best possible transmission but, don't want to buy something that is overkill.
Thank you,

Thanks so much for this information. I have been looking at the cat6 cable with the RJ45 connectors. Good advise on not bending it also.  I think I will also want to upgrade my current FIOS router to a Quantam 5Ghz as well.
@jea48 ,
What are your thoughts regarding Cat 5, 6, 6a?
Is it worth it to go to 6a or Cat 7 or 8?
I am confounded by the choices when related to audio.
Thanks

The price differences among Cat 5, 6, 7, etc. are quite small relative to the cost of your system. Go with 6 or 7 so you won't be thinking about it later.
And, RJ45 is the designation of the type of connector at the end of the cable, not of a kind of cable. That's the connector you normally see as the termination of any category of Ethernet cable.
I used Cat 6A to connect my wireless repeater to my Node 2.  Probably overkill.  I used el cheapo Monoprice cable.  It's very inexpensive and seems to be well built.  I probably should have used megabucks audiophile Ethernet cable, but it's for a bedroom system and sounds great to me. 

The Monoprice meets UL Code 444 and National Electrical Code TIA-568-C.2 fire and safety standards, so it sounds like it should be OK in a wall.  I am not an electrician though and can't say that with certainty.
