Just a stab...
FL has always relied heavily on absentee ballots, so the GOP Legislature there wasn't invested in trying to minimalize absentee/mail ballots by ensuring they are counted last. Same with OH and IN, 2 states with GOP Legislatures who aren't particularly tied to Trump and therefore aren't all in on trying to promote the red mist theory...
The issue in AZ is the GOP Legislature (heavily invested in Trump) and the Maricopa Co election board which is GOP controlled but not heavily tied to Trump. Sheer size is an issue- Maricopa Co is the 2nd largest election jurisdiction in the country and represents 60% of Arizona's electorate...
But as we saw with the "cyber ninja" farce, AZ is full of wackos, and more than a few are in the State Legislature. So they have done things like institute super strict verification processes, which combine with rules on when ballots can start to be processed to slow down the entire process.
Currently "late earlies" (early ballots dropped off ON Election day, can not begin to be processed till all the other early votes are counted. In AZ this year, 100,000 more late earlies were dropped off than in 2020. And since the ballots dropped off thru the weekend and Mon have to be counted first, it's pretty much the late earlies that are yet to be counted... Some insight into required "verification"...
"When people are told to drop off their early ballot on Election Day, those can't be counted that night. You can't just run them through a machine. They have to be signature checked, scanned first, signature checked, then processed by a bipartisan board before they can be counted," said former Maricopa County Recorder Helen Purcell.
Purcell said there has been a massive increase in the number of early ballots cast. Currently, workers are counting ballots that came in over the weekend before Election Day, and on the Monday before Election Day.
"You can't have it instantaneous unless we had a race where we had 60% and 20%," said Helen Purcell.
According to Maricopa County Recorder Stephen Richer, 100,000 more "late earlies" were dropped off this Election Day than in 2020. It's the highest number of early ballots turned in on Election Day in the county's history.
Richer himself has noted that this might spark up a policy debate about the benefits of dropping off early ballots right up to Election Night versus the value of getting immediate answers about election results."
As counting efforts continue, some are asking how other states like Florida get election results so fast while Arizona still has no answer on most of the top races.

NV is a more complex issue. Maybe someone else has some insight into that situation...
