Plus-body rivet nuts are the best option. These fasteners flower into a wide plus-shaped installation base on the backside of the application. This flowering effect provides for plenty of grip strength and greatly reduces risk of cracking the fiberglass/composite application.
Plus-body rivet nuts go by branded names such as Bollhoff Plusnut®, Atlas Plustite®, AVK R-N Series®, CPB Series, etc.
