Existing monitors have good enough resolution, but can't be big, cheap and
high resolution; video wallpaper is more like it.

Curing cancer seems to be one of the simpler applications. A bunch of
glucose powered little robots are injected, they probe cells they encounter
(mRNA expression patterns?), if cancerous, kill. Don't inject too many at
once, or the body's ability to metabolise necrotic tissue may be
overwhelmed. A small initial dose will reveal if healthy cells are being
killed by mistake, if so, inject the innocuous common drug set up as the off
switch for the nanites, and repeat with retargeted nanites.

If by thermal resistance you mean insulation, yes (reflective coated vacuum
pockets in a substrate stong enough to be made sparse without being too
weak). Ability to withstand high temperatures, no, high temperatures cause
atom migration, ruining any nanostructures before melting, leaving you with
a material no better than bulk fabricated.

Solar panels and fuel cell batteries should be fairly easy, and usefully
complement each other.

The biggest use of superstrong materials seems to be megastructures, the
time from making new materials available to building of which will be
several years. Superfast computers can be put to use much more quickly.
