ELI5: How do governments decide how much money to print, to ensure there's enough in circulation? Do they print more when there's a physical cash shortage?

Yes, they get orders from the banking system for cash, along with "old cash to destroy".  To the degree that these are not equal, then they know to make more.  It's not completely effective, as the current coin shortage shows, because there are limits on the governments ability to make different denominations of currency.  It turns out that the machines that make coins are super expensive, custom, machines which limit the ability of the US government to make enough coins right now.
