Interesting discussion.
Apart from what to train, what options are there?
-Extra training in a FFS simulator. Company pays. Not likely.
-Private flying, motor or glider. Fun, but time consuming and expensive.
KISS, people.
Lockheed Martin took over Microsoft Flight Simulator and developed it further.
Prepare3D, P3D.

Buy a high quality 737 or 777 from PMDG. Add it to P3D.

Add a set of flight controls, and off you go. You can train whatever you want.
Raw data, IFR, VFR, ILS, FMC, it's all there.
Low cost. Available anytime.
AND, the model fly by the same numbers as the real aircraft. Do a take off calculation with your company software. Set the PMDG aircraft up with the same weight. The FMC speeds are correct. Customize the model to match your company aircraft.
You need a certain thrust and pitch to keep 250 kts at 10000 ft in the real aircraft. It wil be the same in your PMDG aircraft.
Too much? Nearly all systems in the PMDG 737/777 have been modelled. Correctly. You can practise system failures, and you will get the same indications as the real aircraft.
It's that good. It's time to stop making fun of flight simulators and see the potential. For practice. Transition training.
