FLL feeder final was combined together. Sector was working Aircraft X inbound from the west on the 10L ILS final. The Zulu controller saw a 2300 ft VFR climbing and turning out of the OPF/HWO area northwest bound through the FLL east finals; and tagged it 'Watch2' acquiring the callsign Aircraft Y via ADS-B. The aircraft continued through the ILS approaches just west of PIONN; which has a crossing altitude of 025. Aircraft X had to be kept high and unstable because of the observed traffic. Fortunately the volume was not so much to be dangerous; however had this event occurred during busier times of day; it would have been substantially more dangerous. FLL needs a bigger class C airspace or a class B!
Miami TRACON Controller reported an airborne conflict with an air carrier inbound to FLL and a VFR aircraft.
