Sony’s Clear Image Zoom may be good with video but it’s useless for professional ‘stills’ use as it does not support RAW.
I did give it a try with some bird photography in low light and the results were unusable as noise reduction was not feasible as in the following shot. Yes the image fills the frame (uncropped) but the detail is very poor and the noise too high.:
Much better to use Pixel Doubling technology such as Adobe Photo Enhance pixel doubling.
A utility A7Info displays the active focus point the camera used to acquire focus at time of shooting.
If you are using a Sony camera released prior to 2021 (A7RIv, A9II) then there is no method of reviewing where the focus point was when the shot was taken during post processing.
Note that only Sony ARW files are supported (not DNG).

For more current cameras release around 2021 sony displays the active focus points in Image Edge Edit application.
