I'm loving that aesthetic. I wouldn't change ....much.
Just m.o. from experience: Unless you have knowledge of servicing appliances or know someone, there are certain appliances it might be less headache to stick with something newer.
Stoves really haven't changed that much in 50 years, and they last because there are no moving parts and they have no water in them. "Updating" your stove to a retro harvest gold (or other color) WITH electronic ignition will probably be easier and there are more choices. It's also going to have more presence in the kitchen.
As was mentioned above about the microwave, another good idea that one will get noticed.
A retro 70s refrig would be 3rd on the list <span style="text-decoration: underline;">BUT</span> it depends on what it is and how efficient it is. That late 90s Whirlpool looks good and will be reliable for you.
As for the dishwasher....they <span style="text-decoration: underline;">have technologically</span> changed. They have moving parts and they have water inside so there is issues with reliability. A dishwasher is the most likely appliance to be found as replaced in older homes because of all the usage they typically get. 70s dishwashers also did not have the best reputation as back then they were still a "new" appliance for the home.
Finding a used one will be more difficult.
Finding a WORKING one will be even more difficult.
A novice <span style="text-decoration: underline;">keeping it working</span> will find that a challenge which might take some of the fun out of the retro experience, if you know what I mean.
There is limited presence of a dishwasher: it's just a 24" base cabinet front. It's very easy to do what you've done to any dishwasher that is simply painting or applying a wrap on the door panel and it's probably the best choice for long term peace in your home and enjoyment of the aethetic.
If it were me, and keep in mind I know how to fix retro dishwashers, and I had a (nearly) completely retro kitchen like yours: I would look for a newer (past 10 years) dishwasher or even a new one. I'd look for something quiet, with 3rd rack, and all the newest options.
Then, I would get some harvest gold (or avocado, coffee, candy pink, or whatever retro color you want) contact paper or wrap and simply do the door.
You could even wrap your white microwave sides. It's affordable, easy, and you won't have headaches of service issues.
If you look at the archives, herein, it's not unusual to find people, such as yourself, who were enthusiastic to get "the real thing" and found a 40 y.o. dishwasher and had someone install it.... but now they have a problem. There's no warranty. It's difficult to find service people now who fix those old machines. You get the picture I hope.
Best of luck to you.
