I think that's why he used "horizon" in quotes. Is this
link pertinent?

It doesn't matter what punctuation he surrounded horizon with. There is no cosmological horizon 14 billion light years away.
The link is pertinent. The value for conformal time is ~47 billion years. The particle horizon is 47 billion light years distant.

I agree there are some misconceptions as stated in the
"Misconceptions" section of the following link:

You can't be agreeing with me: I didn't say misconception. I said "completely wrong" and "rubbish". The 14 billion light year horizon is both.

This is getting a bit complicated, but it really depends on how you choose to measure distance (what coordinate system you choose).
The longest time a photon could have traveled is ~14 billion years (total distance = 14 billion light years). BUT, space is actually expanding. The road behind the photon actually got LONGER. The photon is still traveling at the speed of light, but it seemed to have covered more distance because new space was created behind it. In other words, when we look at that photon now, we see it covered 45 billion light years in only 14 billion years. The point is, you can say the "horizon" is 14 billion or 45 billion light years, depending on what you are measuring.
