'Shouldn't the engines be more of a concern than the windows?'
Airliners are designed to fly* with one engine inoperative, so although a drone strike could** take one out of action there's no real risk to life. The 5 hour inspection would be because you need a borescope or similar to check the latter stages in the compressor/turbine for damage and then there's paperwork...
*From a certain point in the take-off run through all stages of flight back to a successful landing.
**Depending on what happens it's not inconceivable that the engine could operate in a reduced thrust capacity.
