My thing here is to cover multiple roles and be useful in many different places.

Arcane Trickster Rogue with Ritual Caster (Wizard)
You have a boatload of out of combat usefulness with Rogue skills, Ritual Caster Wizard, and AT spell slots. Plus you can Booming Blade/sneak attack to do some serious damage

Moon Druid
Druids are already swiss army knives. They have something for almost every situation, then you add on top of that the ability to turn into some amazing forms it's great. You can scout, you can tank, you can summon, you can heal.

Conquest Paladin
High Cha, so you can cover the social skills. You have the spell slots to either smite or cast other spells, you can heal, and there is no one better at protecting the squishies than a Conquest Paladin. Since you are single classing, it may be worth considering going S+B Dex so you are better at stealth as well.

Wow this is great 👍 does cover nearly every pillar and with some redundancies which is important for small groups. I would recommend the dexadin route too so the whole group can stealth especially with Druid providing pass without trace.
