The F125 as drone mothership or underarmed warship

Could the F125's small-craft capacity make it a useful drone mothership rather than an underarmed frigate?

Possibly in concept, but the class is more likely to remain a large ship with too little warfighting capability.

Uncrewed underwater, surface, and aerial systems had been developing long before they became prominent in public discussion. Hypersonic weapons were also an established development path, so neither technology retrospectively explains every feature of the F125 design. The class's boats and aviation facilities could support a drone-mothership role. That concept would need effective embarked systems and doctrine rather than unused capacity for small craft. The more likely outcome is a ship too capable and costly for a coast-guard cutter but insufficiently armed for a proper warship.
