There was a lamp post in my front yard that the previous owners removed and
buried the cable. I am going to put the lamp post back in. When I traced
the electrical for the circuit that was previously used I found that the
cable is on the same circuit that also services the door light and several
outlets in my family room. The breaker in the panel for this circuit is
non-gfci. I intend to replace the existing breaker with a GFCI breaker.
1.) Is there any issue with having a GFCI breaker and the other outlets
including the lamp post on the same circuit?
2.) Also, if GFCI is so much safer than traditional breakers than how come
they are only used in specific places (Kitchen, Bathroom, Outside). Why not
use them everywhere? I assume the answer is probably cost, but when
building a home is it really that much of a cost difference when looking at
the larger total?
There is no problem in having the other outlets on a GFCI protector. They
are required in locations where a ground fault is more likely to be fatal,
which is essentially in damp and wet locations. Minor ground faults that
would cause the device to trip can be a nuisance, so they're generally only
used where required
I wouldn't let ouside circuit share GFCI with other lights/outlets
inside. Most likely fault may occur from outside which will cause
power loss inside. This is inconvenient. My ouside circuits are through
two GFCI, front and back of the house. Bathrooms are also grouped into
two, upstairs, downstairs. This is done through sub-panels.

To illustrate, I have a submersible pump that apparently has leakage to
ground. It has a typical three prong plug for hot, neutral and ground. I use
it for hydroponics where the nutrient solutions that splash around are
mostly salt water (not sodium chloride). I want good protection.
I have found that the leakage causes the GFCI to trip especially when the
pump is turned off. The inductive kick is what does it. The leakage is low
enough so that if I have a good protective ground connection, I do not
worry. Nevertheless, I avoid using that pump whenever possible.

you break the wire bettween the switch and where it goes out in the
yard, install box and gfci which can also be used as outlet.since your
replacing the underground wire this will be easy.
DONT concrete post in place just backfill dirt and tamp well. This way
if you ever need to relocate post or someone puses it over or leans on
it you can easily straighten it
Have you considered running the outdoor lamp post from a seperate breaker on
you pannel? That would be the way I would prefer to go.
In addition to Kitchen, Bathrooms, and Outside outlets it would probably be
a good idea to have garage and basement circuits on GFCI's. After I bought
my house the builder only had installed GFCI's on the bathrooms and the
garage so I added it to all the kitchen, laundry room, dinnet room off the
kitchen, outside outlets, and basement circuits. I also had to rewire one
bathroom because it's GFCI was improperly wired.
