Welcome!
For a while now Linux has been better at most personal computing things except gaming. And for server uses an even longer time.
There are some specific hardware/software situations where you’ll need Windows but it’s unlikely to happen at home. Unless you have very peculiar hobbies.
The typical recommendation in this case is Debian.
I don’t know how hard it is to install since I don’t use it myself. There are a lot of people swearing by it’s stability, even running it for 10+ years on the same hardware without a reinstall.
