Florida's count, whether it goes for Trump or Biden, will not be disputed.
Trump may never fold, but if Florida's count goes against him, all those around him will fold. There's no way to recover from that, no secret stash of hanging chads or ballots that got lost in the mail.
The other swing states have messier voting requirements and messier processes, and there is a lot that could be disputed in states like MI, NC, and WS if one was motivated to dispute it.
One thing to keep an eye out for is shenanigans by state legislatures to try to change the outcome of races for US House and US senate. Remember that the new House and new Senate are supposed to take their oaths on Jan 1, then they are supposed to count the electoral votes together on Jan 6.
