No. The price difference is not trivial. Even the FreeNAS documentation says "If your system supports it and your budget allows for it"

The voltage drop and power loss isn't that big of a deal. The real problem with undersized extension cords is the heat. Try to draw too much current through too small of  a cord is dangerous because the connectors and the cord heats up. It can cause fires. Especially if any parts are coiled up and concentrating the heat.

If you have only Internet service and not phone/TV, you can ask the installer to give you Ethernet from the ONT.

More of why do you want pfsense.

According o the TPLink website, the TL-WR940N has an Access Point mode. It should be a matter of enabling that and it will then function as an access point with routing and DHCP functions disabled. Take note that when you plug the Ethernet cable into it to connect to your actual router, most devices of this type will require the cable be plugged into one of the LAN ports and not the WAN port.

Do you need a commerical firewall? Open-source like PFSense does not fit your need?

There is debate if this doomsday scenario can even happen. I personally don't believe it. Otherwise there would be some story out there about it happening.
 
Also, if there were even a possibility, then the documentation should include such a warning about such an ominous scenario.

$700 or $1200? Why are you comparing those two?

Just get plain old riser cable. There's not going to be enough interference. Shielded cables need proper termination and correct grounding.
 
Plenum cable is used when cable is run through air ways/channels/ducts.
 
If your house is on fire, you have bigger things to worry about. There is plenty of other stuff already present that is bad when burned.

Another option to buy an air compressor. Compressed air whenever you want and useful for other things.

Look at Whitestone Dome. Probably *the* glass screen protector for any curved screen. 

Lol. Don't drop it. Sometimes life happens.

You should do multiple hardwired access points. A wireless mesh network will be far less effective. 

You’re not going to get a 4K projector for $800. 
 
THX recommended screen size at 6 feet is 53”. A 55” TV would be a better buy. Projectors are for getting very large images.

Because children are currently the only way to survive as a species...

You learn by multiple sources. If there are 200 videos that tell you X and 3 videos that tell you Y, then you are probably going to do X. 
 
Learning the the basics of something doesn’t require formal education or “accredited” instructors. 
 
Learning and the exchange of information doesn’t change just because of the medium. 
 
Think about out how much you learn about everything as you are growing up. You learn from unaccredited parents, friends, and strangers. 

And plenty of hobbyist gun owners aren't allowed to be SWAT officers.
 
Just because you go to a "school", pay for an "education", or have a "certification" doesn't mean that you have good information.
 
It is up to each person to determine the validity of the information that they receive and choose how to use it.

Plenty of hobbyists learn welding from YouTube. Your analogy with professional welders would be more akin to having SWAT cops learn from YouTube. 

Lol wat. “If you need computer building lessons from YouTube, you shouldn’t be buying computer parts”

The best thing to do is to install a SSD in your current computer. 

If you decide to use conduit, you should still use exterior cable. The conduit provides more physical protection, but condensation can form inside the conduit and inside the ethernet cable itself. Exterior cables should be gel filled to prevent the condensation from forming.
