Do folks here use humidifiers and just cope with the inevitable
condensation and mold and mildew? Or do they just live with the dry
heated air during winter?

In northern N.American winters, if the furnace has no humidifier
function, a room humidifier helps people feel more comfortable.
Condensation on window glass varies with local indoor and
outdoor temperature and the thermal efficiency of the window
(e.g. 1, 2 or 3 panes.) Interior condensation should be mopped
up once a day. This prevents the development of mildew on
these surfaces. (The medical and structural danger of mildew
on surfaces we cannot see, e.g. within walls, is a separate
and more important topic.)
