How continuous naval control could strengthen British fighters

If the Royal Navy kept control of the Fleet Air Arm after 1919, would RAF fighters develop differently?

Yes. The Navy's need for fighter-based outer air defense would push fighter profiles and supporting technology forward.

Continuous Royal Navy control of the Fleet Air Arm would make fighter-based outer air defense a persistent service priority after 1919. That requirement would push engines, weapons, control systems, and airframe technology rather than affecting carrier aircraft alone. British industry and the RAF would draw on the same technical base. Fighters entering service in 1939 could therefore carry a stronger naval design influence even when operated primarily from land.
