Anti collision lights are beacons and strobes. Normally, strobes are avoided when on the ground, except when taking the active.
Navigation or position lights are normally not run during the day, but on larger aircraft they are, and their intensity is greater. The position lights on most planes are silvered lamps, and are quite pricey (~$40 US each when bought in quantity last I recall).
Generally, on light aircraft, best practice by day is to turn on the beacon prior to engine start, and leave it on until shutdown. Nav lights are run during "dark" periods which includes adverse weather. In bright sunlight, they offer little benefit, and operations I am familiar with don't run them.
On heavier aircraft, including biz jets, the standard practice changes, and the beacon comes on with nav lights at startup, and normally those lights run until shutdown. When on a busy ramp at night, it is common practice to leave nav lights on to help bring attention to the wings and tail, even though the engines are off, and the aircraft may be stationary.
While you may not see it at an FBO (as their ramps are well lit, and they don't always have access to the aircraft interior), many freight ops and corporate flight departments will turn on the nav lights when tugging an aircraft on the ramp at night.
Many companies have lighting policies in their procedures which may go beyond this.
14 CFR 91.209 provides general guidance.
§ 91.209 Aircraft lights.
No person may:
(a) During the period from sunset to sunrise (or, in Alaska, during
the period a prominent unlighted object cannot be seen from a distance
of 3 statute miles or the sun is more than 6 degrees below the
(1) Operate an aircraft unless it has lighted position lights;
(2) Park or move an aircraft in, or in dangerous proximity to, a night
flight operations area of an airport unless the aircraft -
(i) Is clearly illuminated;
(ii) Has lighted position lights; or
(iii) is in an area that is marked by obstruction lights;
(3) Anchor an aircraft unless the aircraft -
(i) Has lighted anchor lights; or
(ii) Is in an area where anchor lights are not required on vessels; or
(b) Operate an aircraft that is equipped with an anticollision light
system, unless it has lighted anticollision lights. However, the
anticollision lights need not be lighted when the pilot-in-command
determines that, because of operating conditions, it would be in the
interest of safety to turn the lights off.
