Apple stuff is pretty well optimised so you don’t need really powerful kit, especially if you are just doing basic things.
Having said that, if I wanted longevity I would buy the newest iMac I could afford with:
- at least a quad core cpu
- at least 8gb Ram, ideally 16gb, or make sure you get a model with the door at the back that allows you to upgrade easily
- An SSD for storage, don’t buy a fusion drive or HDD
