Observed light not moving

This one was subtle, most people would not have noticed anything strange. It is simply a stationary illuminated object.
I was on the balcony of my 27th floor condo (on the beach), which looks to the west, where I often enjoy a sunset. One evening, I observed a stationary light to the SW, making it unusual for the busy airspace. Would have said it's a helicopter, except there was no noise. While sitting on the balcony, helicopters can often be heard at a range up to 5 miles. Made a brief video with my iPhone 12 to look at later. Then forgot about it, until a week or two ago; I went to clear out my iCloud storage of old videos and photos. Took another look at it, and after zooming in, it became apparent it was not an approaching aircraft landing light. It showed a polyhedral shape to it, and seemed to show an opal like color that shifted and pulsed, but remained stationary. After enlarging, there were no apparent red or green aviation position lights. The camera seemed to retain approximate focus with the contrail remnant in the far background.
I would estimate the light/UAP was maybe 3 or 4 miles east of the KFXE Fort Lauderdale Executive airport, the light being approximately 3 miles away to the South West from my position, and FXE being 6 miles away to the WSW. My ballpark estimate on the altitude would be about 2500 ft, which would be very unusual for known aircraft...the airspace boundary between FXE tower and Miami Approach/Departure is right at 2400AGL... as I have often flown out of FXE on IFR flight plans, I know that they do not assign aircraft that boundary altitude...it would create confusion as to which controller had that target. While aircraft often climb or descend through that altitude, they would not appear stationary. I did not call FXE tower, as I noted nothing unusual until some 20 months later. (Didn't bother to look at the video in detail for some time.).
I am a retired Navy CDR (O-5), an ATP rated pilot with + 17,000 hours in some 60 types of aircraft. I am a retired major airline pilot, and have flown scheduled passenger service out of FXE airport. I also keep my twin engine Piper Seneca nearby and often fly in this airspace.
This is my 4th observation of something strange, that I could not explain.
I am also a former Field Investigator for MUFON (FL).
I tried to upload the original format, but when exporting a video, Apple changes the format. If the upload isn't a full resolution view of the original video, please have someone contact me for a better way to upload. Would also appreciate someone with better video exam/enhancement skills to shed light on what this object may have been.
To me, without any other explanation, this remains a simple UAP.
My sources at MUFON tell me there were two other reports of "Orbs" within 24 hours of this sighting in other locations in SE Florida.
