I am like 90% sure it was cranking slowly because it was an old weak battery out of another one of my vehicles , it was also cheap so I really need to invest in a new battery anyway

It could be as easy as not enough grip to roll it over to things as starter bind, torque converter not seated in pump binding the pump gears,
I had a vehicle come into my shop and when they had installed the new/used motor they had left the old pilot bearing in the end of the crank. By doing so it had shoved the torque converter back into the pump gears and it's housing. When converter was unbolted from the flex plate the flex plate unbowed and there was a 1/4" to a 3/8" gap between the two.
As it's a automatic everything should freewheel intill the engine is running creating fluid pressure with the front pump

Ok - that may explain the slow cranking with starter but not the other turning by hand.

I am really starting to think it's the neutral safety switch or it's misaligned shift cable... I actually just got outside to look at it but decided to put the battery on the charger for a bit maybe I could use it for now until I can go get another

I had missed the point that it spinns by hand in neutral - shift cable or neutral switch should not stop it from spinning by hand - it should free wheel as long as the engine isn't running - and everything should spin free until hydrolic pressure is built up.
If the torque converter isn't seated right and has jammed the center input shaft and putting enough pressure thu out the transmission to bind all internals the parking paul will stop it from turning.
If you have internals bound that bad it may have damaged the transmission - time will tell -
Unbolt the torque converter from the flex plate, when unbolted torque converter should spin free by hand.
