Probably the most significant effect would be that we would experience a total solar eclipse once every 28 days (or so) if the moon's orbital plane were exactly the same as the plane of the ecliptic.
Solar eclipses would be much more frequent
If the Moon's orbital plane were exactly the same as the ecliptic, there would be solar eclipses at every new moon and lunar eclipses at every full moon. They would be ordinary, and we would lose our sense of wonder about them.
ecliptic but its really a plane orbital radius
The planet Uranus rotates on an axis that is tipped about 90 degrees to the ecliptic.
All of the other planets have an orbital path that is within six degrees of the ecliptic. The celestial object formerly known as planet Pluto had an orbit that was about 17 degrees off the plane.

Because the Moon's orbital plane isn't exactly the same as the Earth's orbital plane. The Moon's orbit is a bit tilted compared to the ecliptic, so we only have eclipses when the Moon happens to be either new or full just as the Moon passes through the ecliptic.
The plane of the Earth's orbit around the Sun is called the "ecliptic". Most of the other planets and moons orbit in planes that are close to the ecliptic, but none of them have orbital planes that are exactly the same. The Moon's orbital plane is about 8 degrees angled to the ecliptic. So most times, the Moon is either above the ecliptic at the new or full, or below it. It is only when the new moon is on the eclliptic that we have a solar eclipse, and only when the full moon is on the ecliptic that we have a lunar eclipse.

The ecliptic. Because it is the plane that contains the earth as it orbits the sun, by definition it is also the plane that contains the sun as we observe it in its yearly journey through the stars.
The planets don't all orbit the Sun in EXACTLY the same plane - there are small variations. The plane where Earth orbits is called the Ecliptic; other planets orbit fairly close to that same plane.
The planet Uranus rotates on an axis that is tipped about 90 degrees to the ecliptic.
The lunar nodes are the orbital nodes of the Moon, that is, the points where the orbit of the Moon crosses the ecliptic. The ascending node is where the moon crosses to the north of the ecliptic. The descending node is where it crosses to the south.
All of the other planets have an orbital path that is within six degrees of the ecliptic. The celestial object formerly known as planet Pluto had an orbit that was about 17 degrees off the plane.
