We currently do not compress outputs when generating GeoTIFFs. This is not ideal.

I think we've got some room to improve, especially with modern GDAL and other dependencies.

We should be able to do band interleaved with predictor 2, and maybe ZSTD+LERC for DEMs and maybe JPEG + transparency band for orthophotos...

I would love to use the latest and greatest, just not sure if older/proprietary programs will be able to read the results afterwards. Needs to be balanced for interoperability.

DEFLATE + Predictor 2 and ZLEVEL 12 or 9 should be about as good as we can get while keeping things bog-standard then.
