Change the oil before you park it. All three of my cars are more than a decade old and the oil accumulates some junk/water in the months between oil changes. I don't want to deposits to settle into any passages or valve stems so I change before I leave it for an extended time. I disconnect the battery and don't bother with the potential hazards of leaving the battery on a trickle charger.
If I had something super fancy like a 2018 Hyundai Elantra, disconnecting the battery is as far as I would take it.
Changing oil is an overkill unless you are going to store your car for a few years. If you want to be that conservative dump the fuel stabiliser in your gas tank first and inflate tires a few psi higher
