Electrum is in my opinion the best option for a desktop wallet. It is available on all three systems (Windows, Mac, Linux), and is one of the most popular and safest wallets for Bitcoin.
Bitcoin's Electrum wallet is also extremely light, which also makes it very fast. Using it is not complicated at all, although it can be a bit difficult for new users.
Unlike most easy-to-use wallets, Electrum doesn't really provide hints or tips on their features and how to use them, so discovering all of that is up to you.
Also, it only supports Bitcoin, so it's not the perfect option if you want to diversify your crypto assets. However, it is well known and respected in the crypto industry, so if you don't mind the fact that its user interface is not very polished and intuitive, it will be an excellent choice, a distraction-free solution for you.
