Availability of 5-Ton Variable Speed AC and Air Handlers in South Florida?

Hi All, I've had a good professionally prepared Manual J and Manual D prepared and I need a 5-ton AC / air handler with new ducts. While I know no one "needs" fully communicating, variable speed, high-end AC units and air handlers, I really prefer them; however, I'm hearing that Trane's 5-ton XV20i with TAM9 or XV18 with TEM8 are either not being produced, backordered, or have "lead times" of 3 to 6 weeks, which sounds like a best case scenario estimate. I'm hearing similar things about Carrier's Infinity products (24VNA6 / FE4A or 24VNA9 / FE5) and Lennox's Signature / Elite products (SL28XCV, XC20, and EL18XCV with the CBA38MV or CBA27UHE). As pros, are you seeing any availability of 5-ton variable speed units, believe the situation is getting better, or would advise me to move on to single / dual-stage units as the supply chain continues to be disrupted for the foreseeable future? Thank you!
