Which model air handler?
For a new replacement heat pump looking at Bryant Evolution system.
3 ton, 2 stage model 286BNA03600
variable speed model FE4ANB006T00
The FE4A fan coil comes in several different capacities but the values overlap.
Which is the correct one either the 002, 003, 005, or 006? Also what size heatstrip?

It is likely that a couple of those air handlers are rated matches. The larger models typically yield higher performance (capacity and efficiency) numbers. However some of them aren't ideal for every situation due to their physical size. Heat strip size depends on your home and calculated heat loss -- and the electric run to the unit. Likely 10 or 15 kW.
