I love goldfish but they are a lot of work, my main tank when housing 2 goldfish was a water change and gravel vac very 2 maybe 3 weeks, same tank with less filtration and tropical community water change at 3 maybe 4 months and mainly because I feel like rearranging rather than urgent keep them alive maintenance.
So I understand the dilemma you are in, I say try some "easier" fish you'll probably enjoy it and you might find the reduced stress of not having to manage a population a nice change. My egg layers do breed but never get out of control as I do nothing to protect eggs or fry aside from feeding fine powder foods every now and then and lots of hiding places due to my plants and hardscape.
The joy of the hobby is with the right tweaks tanks can be set up and stocked to provide joy without being a burden on time and strength.
However its the breeding you enjoy the most maybe get into shrimp their bioload is so low they rarely crash tank so you can leave it be when your body needs you to and no harm will come to them.
You will probably always have guppies though but maybe not in every tank
