2000 years ago and more the astrological signs overlapped with the constellations. Signs and constellations drifted apart in the western tropical (sun-based) zodiac due to precession of the equinoxes, but signs and constellations are still more or less overlapping in the Vedic (sidereal) zodiac. Today the western tropical and Hindu sidereal systems are about 23 degrees apart.
Of course, none of the constellations occupies exactly 30 degrees on the ecliptic. The Babylonians invented 30-degree signs around 500 BCE to make it easier to predict eclipses.
As you mentioned, there is a kind of constellational astrology for astrologers who work with fixed stars.
Medical astrology is one branch I can think of where signs and houses carry much the same meaning. The old medical astrology goes by parts of the body. So Pisces and the 12th house both represent the feet.

Semi-correct on houses, incorrect on constellations, correct on the rest of it. Zodiac signs actually have nothing to do with constellations. They're simply measurements of the ecliptic based on the solstice and equinox points.
Constellations have some association with the zodiac signs they're named for, mainly due to their proximity to those signs at the time our current astrological system was established, but they're separate from signs, and there's no real astrological significance to constellations. To certain individual stars in them, yes--fixed stars are a whole other layer of astrology, and many of the fixed stars used are in the constellations named for the zodiac--but most fixed stars have a quite different symbolism from the constellations they're in, and the only association between a fixed star and the zodiac sign it's in is that the zodiac sign is used to locate it in a chart.
Houses are also separate from signs. When interpreting an astrological chart, the combination of a sign's meaning and the meaning of the house it's in is relevant, but if you're just considering the zodiac signs alone, houses are irrelevant.
