If a newbie wants to hold Bitcoin, I will recommend electrum wallet because it is user friendly and has good features. Although it is also connected to internet but it is more secure and reliable since several people have used it and have testified here in the forum.
Electrum can be used offline and as a cold storage too.
You can create your electrum wallet on an offline device (preferably on an airgapped device) and sign your transactions there.
Take note that you need internet connection only when you want to check new transaction you may have received (so that you can make an unsigned transaction) and when you want to broadcast a transaction.
