In a small GA aircraft, in which phases of flight will you normally use mostly
trim to adjust pitch, and in which phases will you normally mostly use the
yoke?

Here's a good page with more detail along Dudley's reply:

Trim history
The trim tab or servo trim was invented by Anton Flettner, a German
aeronautical engineer. He started work in 1905 for the Zeppelin
Company. Died in 1962.

Trim
Most aircraft have single axis trim for the elevator. Airliners have
three-axis trim for the elevator, rudder and ailerons. Trim is used to
correct for any forces that might tend to counter your selected flight
performance. Trim allows the pilot to relax. A pilot who cannot trim
will be an exhausted pilot in a short time. It takes only a couple of
flights for a pilot to realize the benefits of trim. The best check
for proper trim setting for any flight configuration is to let go of
the yoke completely and see what the nose does.
