Does anyone here have experience with types of wine (see details)

I want to buy a nice bottle of wine for an upcoming special event, and my experience with wines is pretty limited. I stopped drinking wine when my wife was diagnosed with pancreatitus about eight years ago and she couldn’t have alcohol anymore, but she says it is fine if I want to get something nice to serve at the party. I will be serving various types of red meat, and I have a bit of a sweet tooth. I’m looking for a wine that goes great with grilled meats, isn’t too bitter, and won’t cost me an arm and a leg. Something under $30, if possible.
