Raster Data Management Advice

I would set up a polygon of the bounding box (in the native projection) of
each raster source, and use fields on those polygons to store the details
of interest: xmin,xmax,ymin,ymax, dimension, resolution, crs, and your
other details. Then hone in a areas of interest for different tasks to see
what set of overlapping data you have for it.

There's a lot of fanfare about STAC, but it's really just a JSON-format
with some of the information you could store on a simple polygon dataset
...with STAC as with so many formats you'd have to shoehorn your data into
that more restrictive form (you can always spit out STAC as a side product
of your own rich summary for less sophisticated uses).

The crux is keeping the details of the source's native
projection independent from the representation you use to query it
spatially IMO, just record what's there. Further, the GDAL warper app-lib
(one level below the gdalwarp.exe) is the right tool for doing general
reads, of any number of sources into one specific window of your choosing
in any projection (you could use your dataset described above to limit
which sources get included). You can easily see what you'd get by merging
any number of sources together, and of course more nuanced situations like
a sensible background with more detailed layers merged over that is very
valuable.
