In both upstairs and downstairs bathrooms, whenever we flush the

water coming out of what is supposed to be the cold faucet is very hot.
After about 30 seconds, it will go back to cold.

Recently, we had a flood in our upstairs when the black floating ball
in the tank of our toilet broke while we were not home. 80 gallons
were deposited below. When repairing the toilet, the plumber noted
that there was hot water filling up our tank.

Does anyone have any ideas for these two things to be happening? I
don't know if they are related or not, but I am open to suggestions.
The plumber thought that the filter in the shower might need to be
changed and could be causing the issue.

Thanks in advance,

Check to see if your toilet supply was plumbed to mix a little from the
hot water supply in with the cold to prevent a tank full of cold water
from sweating on the outside if the humidity is high.

It might have been done that way and has gone out of adjustment.

Though I'd more likely go with the suggestion that you see if the hot
water filling the tank stays hot for a couple of minutes of flow by
holding the flapper up by hand so the fill valve stays open and water
keeps flowing in. That'll give you more to go on. If it stays hot
continuously after the sink water cools down you've got more to look for.

I once ran into a toilet which must have been installed by a drunken
worker. It WAS fed from a hot water supply line, and I guess no one
noticed it until after they'd closed up the wall.

Something about your story bothers me though. Did your plumber explain
how the hell 80 gallons of water "got deposited below" because the float
ball broke? Isn't that just what the overflow tube in the tank is there
to prevent?

Did the ball break off its arm and then manage to float around and end
up covering the top of the overflow tube, thus blocking it off? That, or
a badly clogged drain is about all I can think of which would cause that
"water deposition" event to happen.
