I'd add the Arizona Trail
for consideration. You'd be more likely to get the solitude you're yearning there than in Florida.
Most places that I'd know about for some real solitude would tend to be way cold in the winter. So those are pretty much out. I was thinking about AZ also, but in the MTNs there it is still going to often be 20F and occasionally minus 20 or even colder. ( my personal low at Flagstaff: minus 23, with reports of minus 30 - 40 in some remote areas that morning ) But if you could keep the elevation reasonable, it might not be too bad. Many miles of this trail would probably be at OK elevations, probably plenty to keep OP busy. Some places might be really cold. But not near as bad as some of the places I would recommend if it was summer. Remoteness and solitude should be way up there.
That Texas rec from sargevining has some real possibilities. Plenty of solitude at Big Bend! Temps should be OK.
It seems like the best bet is the AT as some have suggested. At least if a severe cold snap occurred it would not be too hard to escape to a nearby town.
But those FL/AL/GA recs seem the best bet for having temps that won't stress you.
