Which tangible effects can major solar storms, resulting from events like coronal mass ejections, have on Earth-based infrastructure?

Answer

Knocking out power grids, disrupting GPS navigation, and interfering with satellite communications.

Major solar outbursts generate solar storms whose effects can include causing spectacular aurora displays but also potentially damaging terrestrial infrastructure such as knocking out power grids and disrupting critical navigation and communication systems like GPS.
