If you're doing the full future proofing thing, I might consider fibre
for
higher bandwidths.* Terminating it is easier than 10GBASE-T (unless your
equipment only has an RJ45 and nothing else).

cat5e can be used for MultiGig (2.5 or 5.0 Gbit), but so far I've only
seen APs using that rather than PCs, but it seems gaming laptops are
starting to support it.

Gamer desktops are also starting to support it - eg chips from Aquantia.
However the current lack (as with 10G) is affordable switches.

Another work round is link aggregation - i.e. using multiple 1G links
aggregated at layer two on a smart switch.

For example my NAS connects to my LAN via 4 x 1G ports aggregated
together giving it 4GB/s total connectivity. Needless to say the
bottleneck is the single 1G connection to the desktop - but at at least
it can saturate the connection to more than one machine at a time.

I did that at work last time around (going 10g this time

The main disadvantage (apart from extra cables) is the hashing algorithm
(used for link selection for any given packet) tends to be keyed to the
client and remote IP - so all the traffic between 2 devices will tend
(in all forms of LA I've used) to get stuffed down one link.
