That is exactly Linux Mint ( https://linuxmint.com/ ) . I encourage you to give it a try. It is what I have settled on after 25 years of using linux, and trying near about every distro in existence.
I'm aware of Linux Mint, but I always dismissed it because of Cinnamon without giving it much thought. Looks like KDE can be shoehorned in without much trouble.
