Mint is great and is absolutely enough for most people using computers, still as of now. It comes with its limitations though:
By default it runs pretty old kernel. This is fine if your hardware is at least 3 years old. It allows to easily switch to newer kernel with just few clicks, but I expect newbies to not be aware of this at all. Oh, and I don’t know if it offers some custom kernels like tkg etc, which some might want to squeeze best gaming perf etc.
Cinnamon is still limited to X11. If you have multi-screen setup, VRR, mixed refresh, mixed DPI etc, it’s better to switch to Wayland. Plus, Xorg server gets less and less maintenance and development. All the innovation moved to Wayland, so the experience on X will remain pretty stale.
The Ubuntu base makes it so that for 3rd party software you either need deb packages or PPAs. Some will argue (me included) that it’s not the best solution
All of the above can easily be irrelevant to you and Mint is just perfect for what you need. It’s important to point out limitations of that choice, but crapping on it because you don’t like it is just pointless fuss
