Don’t feel bad, that’s almost a rite of passage for pool owners. I think most of us have done it at least once. If the equipment pad stayed dry and nothing electrical got splashed, you’re probably in good shape.
One thing I’d check after a big overflow is the chemistry. When that much fresh water gets added, it can dilute a few things more than people expect. Stabilizer and chlorine tend to drop the most, and sometimes alkalinity shifts a bit depending on your fill water. It’s not usually dramatic, but worth testing so you don’t get surprised a couple days later.
I’d also keep an eye on filter pressure for the next day or two. Sometimes when the pool overflows it washes dust, mulch, or dirt from the deck back into the water and the filter ends up catching it later. If the pressure creeps up a few psi sooner than usual, that’s usually why.
Otherwise you’re probably fine. The good news is overflowing the pool is usually harmless compared to the opposite mistake of letting the pump run dry. A timer on the hose is a lifesaver though, I started using one after doing the exact same thing.
