If you need a really long cable, you might consider WiFi instead.
Something like a DLink DAP 1160 will convert "wired" to "wireless"

modem which is some inconvenient distance form the TV.

Does the lower speed of WiFi compared with ethernet become relevant
when dealing with TV (video) data?

Potentially yes... but it does depend on what you are using the
ethernet connection for.

If all you want is access to Youtube via the internet, then it makes
little difference, since whatever wifi speed you get will still be
well in excess of most broadband connections.

If however you have a DLNA media server stuffed full of HD movies etc,
and you want to stream them to the TV, you may find the wifi ruyns out
of puff. Hence the popularity of "Homeplug AV" data over mains gizmos
for this application.

WiFi is quite quick.

Sometimes... much depends on if you are running 802.11 n or g. And with
g, in particular how many folks in the neighbourhood you are being
forced to share spectrum with. That is before you start taking into
account losses due to range or attenuation from the building fabric.

I can saturate my 18M DSL connection with ease using WiFi.
The laptop will be doing other things over WiFi at the same time.
I can be streaming a HD video into the laptop and then out to my TV,
both over the same WiFi without any problems.
That is on either band although I prefer to use the 5G band.
