Hello susan_california and thank you for your question
To directly answer your question "Can comfort or cruiser bicycles be
taken off-road on occasion?" the answer is yes, provided it is for
"light off-road recreational use"
I would say, given that the profile of the future users is 50+ in age,
and given that seniors tend to prefer the comfort or cruiser bicycles,
and given that it is generally accepted that comfort or cruiser
bicycles can go off road (provided that it's not "overly rough and
tumble") I would say that there should be no problem.
See below for some opinions and descriptions:
"Description
Comfort bikes are sporty all terrain bikes which are designed to offer
superior rider comfort.
The frame is similar in style to a mountain bike, but the riding
posture is designed to be more upright to reduce pressure on the back
and shoulders, such bikes are usually fitted with an adjustable
handlebar stem which allows the rider to alter the sitting posture.
The components are designed to increase rider comfort rather than to
decrease weight, often featuring a wide comfort saddle, suspension
forks, suspension seat-post, comfort grips and easy to use gears. They
are often fitted with wide smooth rolling tires that are suitable for
on road riding and gentle trail riding.
Good Points
Comfort bikes are general purpose bikes which are ideal for pleasure
riders, new riders, or for those returning to cycling after a break
from the saddle. Comfort bikes are ideal for pleasure biking on bike
paths and are also suitable for commuting, gentle off road trail
riding and trekking.
Bad Points
Comfort Bikes are designed for comfort rather than speed so they can
be slightly heavier than hybrid or mountain bikes. They are not as
fast on the road as a hybrid bike or as stable off road as a mountain
bike.
Should I buy this type of bike?
If you plan to use your bike for leisure biking and value your comfort
but want a bike that looks and feels sporty, comfort bikes are for
you. Don't buy this bike if you want to compete on or off road."

"If you're looking for a bike to ride on the pavement most of the time
but want to ride hard-pack fireroads and horse trails occasionally,
this is the bike for you."

"Hybrid and Comfort bikes are built for comfort a compromise between
mountain and road bikes. They enable you to keep your back in a more
upright position. These bikes are excellent for use on both pavement
and dirt trails but are not intended to be a competitive quality road
bike or mountain bike.
Hybrid and Comfort bikes often include a suspension seat post to
absorb minor bumps on the road or path. Light front suspensions make
small bumps easier to ride through which places less stress on the
wrists and shoulders. Hybrid bikes have larger 700C size diameter
wheels and 21 to 24 gears, while Comfort bikes have 26 inch wheels
with wider tires.

"comfort bikes" which offer straight handlebars but upright riding
position, medium-width tires, and well-cushioned seat. Great choice
for urban and light off-road recreational use,"

"Comfort bikes
These are modified mountain bikes designed to be more tame for the
less aggressive rider who values comfort. They have wide, smooth
treaded, medium pressure tires, high handlebars, an upright riding
position and a wide, soft seat. Advantages: Smooth, soft, stable ride
Disadvantages: Slow on-road and less nimble off-road"

"Comfort bikes. These are specialized mountain bikes or hybrids with
more upright riding positions, softer saddles and lower gearing.
They?re built for, as the name implies, comfort, but are also designed
to perform well."

Comfort Bicycle
The original runaway popularity of mountain bikes was mainly related
to their greater comfort for casual cyclists, compared to the
drop-handlebar , skinny-tire sport-touring bikes that had been the
predominant adult style through the '70s and early '80s.
As mountain-bike racing became more organized, mountain bike designs
started to morph into a more competition-oriented riding position,
with longer top tubes , lower handlebars, narrower saddles, shorter
wheelbases and more upright frame angles .
By the late '90s, this trend had gone so far that many casual/beginner
cyclists were finding mountain bikes uncomfortable.
In response, the industry came up with what is commonly known as a
"comfort bike." Typical comfort bikes resemble mountain bikes in wheel
size, brake and gear equipment, but also differ in several ways:
Shorter top tubes, for a more upright riding position.
Taller, often adjustable, handlebar stems, also for a more upright
riding position.
"Riser" handlebars, also for a more upright riding position.
Wider saddles with springs (and/or suspension seatposts.)
Smooth, wide tires for quiet and comfort on smooth surfaces.
Lower bottom brackets for easier mounting/dismounting .
In many respects, the comfort bike harkens back to the riding
style/position of the classic English roadster , only with modern
gears and brakes.
Comfort bikes are often seen as slower, stogier versions of "hybrid"
bikes, and are targetted at pretty much the same market.

And from the news groups:
"There are mountain bikes fitted with cushy seats, suspension seatposts, and
riser handlebars that are often labeled "comfort bikes," although
manufacturers seem to have fun inventing new labels for this category. These
have 26" tires, and can be fitted with either knobby or street tires. They
generally have mountain gearing. They're suitable for off-road use on mild
terrain, and will give you a comfortable ride on the street. But they're
relatively slow, and probably not the best choice if road/street riding is
your primary purpose"
