<p>Your classification is correct if the purpose is - why they were invented initially. However rather than the task based taxonomy, CNNs are better studied on the basis of what different they are doing. Initially CNNs were designed for image classification, but the same network works for Object detection with slight modifications in last layer. For example, Faster RCNN (designed for Object detection) can use any of the architecture designed for classification such as VGG, ResNet etc (<a href="https://www.researchgate.net/figure/Comparison-of-multiple-faster-R-CNN-backbones-The-evaluation-metric-is-MAP05IoU_tbl2_337017443" rel="nofollow noreferrer">link</a>). Similarly Faster-RCNN can be modified to do segmentation task in Mask-RCNN architecture (<a href="https://arxiv.org/abs/1703.06870" rel="nofollow noreferrer">link</a>).</p>
<p>Here is a chart showing evolutionary history of deep CNNs showing architectural innovations (<a href="https://arxiv.org/pdf/1901.06032.pdf" rel="nofollow noreferrer">source</a>)

<p>Here is another taxonomy showing different categories based on architecture style.
