supergravity in dimension 4.
The maximally supersymmetric $N = 8$-version arises from type II supergravity in 10 dimension by compactification on a 6-torus.
The $N=1$-version arises from KK-reduction via M-theory on G2-manifolds. This hosts the super 2-brane in 4d.

Perturbative finiteness properties of gauged 4d supergravity from $N = 8$ ungauged 4d supergravity is discussed in BCDJR 11, p. 24:
Another question is whether $N = 8$ supergravity might point the way to other, more realistic finite (or well behaved) theories of quantum gravity, having less supersymmetry and (perhaps) chiral fermions. One step in this direction could be to examine the multiloop behavior of theories that can be thought of as spontaneously broken gauged $N = 8$ supergravity [73], which are known to have improved ultraviolet behavior at one loop [74].
and Ferrara-Marrani 12, p. 12:
Another interesting aspect [21] which should be implied by UV finiteness of $N = 8, 6, 5$ supergravity in $D = 4$ dimensions is that their gauged versions should be possibly UV finite, as well. Roughly speaking, this is related to the fact that gauging may be regarded as a spontaneous soft breaking of an unbroken gauge symmetry, and UV properties should not be affected by such a spontaneous breaking, as it happens in the Standard Model of electro-weak interactions.
