Caldera-forming eruptions do not involce lava flows but massive plumes of ash and pumice. The material produced is usually rhyolite. After a caldera-forming eruption, however, the composition can shift, especially since eruptions can be triggered by the mixing of different types of magma.

No. Caldera and shield volcanoes are quite different. Shield volcanoes usually undergo effusive eruptions, the least violent type and produce basaltic lava. Caldera forming volcanoes erupt explosively and are the most violent. They generally produce rhyolitic lava.

Does granitic lava come out of a cinder cone volcano?

No. Cinder cones erupr basaltic and occasionally andesitic lava. "Granitic" lava, called rhyolitic when it is erupted, erupts primarily from composite volcanoes (also called stratovolcanoes), and some caldera volcanoes.
