What band are you looking to operate on? I’d say most of us got our start on repeaters so I’d say that’s the place for a simple beginner voice transmission. If you haven’t seen it yet you can use this site to help find ones near you:

Otherwise there are 2m and 70cm calling frequencies, I believe 146.52 and 446.00, but repeaters would be more populated.
