Hmm... okay, working from your list what I am aware of from my DMing includes the following
Potentially Distorting
- Crossbow Expert with Sharpshooter and Archery, especially as Battlemaster applying Maneuvers from range
- Polearm Mastery especially with Variant-Human Paladins
- Polearm Mastery with Sentinel
- Crit-focused Great Weapon Mastery, especially Half Orc Fighter Champion / Totem Barbarians
- Shield Mastery with Dueling and potentially a dip into Rogue for Athletics Expertise (also see next below)
- Swashbuckler with Battlemaster multiply triggering Sneak Attack (added to above)
- Lore Bard/Diviner Wizard probably using Lucky and Bane or Bless
- Druids milking the hit point refresh on changing
Reasonable but can be Strong
- Eldritch Blast with Agonizing Blast and Eldritch Spear (if you want range, this beats most things) possibly with Distant Spell (600' range) or Quickened Spell applied (cast it twice)
- Monk Martial Arts with Mobile and possibly Wood Elf
- Greenflame Blade or Booming Blade are conditionally good depending on multiclassing
- Poison use depending on accessibility in your campaign
- Wizard milking Fighter for Action Surge (cast Fireball twice to start the combat)
- Hill Dwarf Life Cleric possibly going into Celestial Warlock
- Archfey / Pact of Chain Warlock milking magical familiars possibly with Magic Stone
- Variant Human Shadow Monk Assassin hoping to milk Assassinate (really only good for one round of a combat and quite conditional)
- ...there's really a lot of possibilities in this category: too many to list and no doubt a lot my group hasn't found yet
Sneak Attack is pretty much average and frankly, straight Wizard for 11 levels beats all of them.
I like this list. A few more.
