All assets - checking, saving, investment accounts have payable on death so they don't go through probate.
All real estate and vehicles have both names, and title goes to spouse on death.
All insurance up to date and beneficiaries updated.
If there is a need for a trust make sure it is created/up-to=date with a lawyer.
I lost my dad a few years ago. The one thing I wish he'd done is downsize the house years before he even became ill. But that's one thing you've already taken care of.
The one thing I personally would do for myself is spend some time each day at rest, visualizing helpful atoms and molecules in your body converging on and merging with those that are sick and making them well or benign.
