Your modern Fortran book looks pretty good.

I'm always sad that the power systems industry has mostly moved from Fortran to C++ as the Fortran is much easier to read and doesn't make overzealous use of OO principles.

I use a lot of Python for process automation and data analysis. If I had to put numerical code in production it would probably be in either Fortran or Julia. My problems with Fortran usually boil down to libraries for certain things like database access. I did a little googling and there is some ODBC support, but it doesn't seem to be very good.
