Looking for the Perfect Class to Complete Our Party

As the title suggests, my friends and I are playing through the campaign for the first time. They've all chosen builds that suit their playstyles:

• Paladin/Rogue (Thief)
• College of Lore Bard
• Evocation Wizard

The problem? I'm the only one who hasn’t decided on a class yet. I’d love to pick something that’s at least A-tier and complements the team well—ideally, something that helps tie the party together.

I’d really appreciate any suggestions or advice on what might work best in this setup. Thanks in advance!
