"It's now difficult to find high end washers and ovens without these features."

Don't buy high-end consumer units, buy industrial units instead. They won't have any fancy features like automatic program selection or whatever, but they will wash your clothes and cook your food for decades, and can stand up to uneven loads and abuse, and they can be repaired if they ever break.

I refuse to let any additional "smart" things into my life. I want buttons and manual controls, no internet connections.

I don't even want any program buttons on my microwave oven, I want exactly two knobs, one for power and one for time.
