Yes, Cleric, Rogue, and non-Valor Bards are the best bets for a True Strike build. Others are possible, but the spell doesn't synch with Extra Attack.
All of those need to get the spell through Magic Initiate (Wizard), though.
High Elf also works, now that they can freely assign their species Wizard cantrip.
The thing with the new version of True Strike is that unlike previous weapon cantrips, it works best when your caster stat is prioritized. There are some interesting interactions, though, and here are some of the ones with better potential I've found.
A Cleric or Druid using True Strike with a Musket. This one needs either High Elf or Magic Initiate. Both classes want to prioritize their casting stat, both classes can get martial weapon proficiency easily, and both classes only make one enhanced attack so they don't care about the limitations of either True Strike or the Musket. Your spell slots are still stronger, but it's a little better than a basic attack cantrip. I'm a kinda tempted to make a Druid frontier mountain man, Davy Crocket style.
An Arcane Trickster Rogue that goes Int primary and Dex secondary. It's easy for AT to pick up True Strike from their subclass. Going for this build has its pros and cons. You get slightly better spell DC, slightly worse Cunning Strike DC. Your damage is a little better thanks to True Strike, but your AC will be a little worse. The big gain is that it's easier to take Telekinetic for ultimate Mage Hand shenanigans. You just may want to use a whip or shortbow.
A Celestial Warlock stacking the benefits of Agonizing Blast and Radiant Soul for triple Cha modifier to their one weapon attack. This is the budget version of the same build with Green-Flame Blade. It does a bit less damage than either using GFB or going traditional Blade Pact, but there are two upsides. One is that it takes fewer invocations; you don't even need Blade Pact if you use a Simple weapon. The other is that it works with shortbows and light crossbows, if for flavor reasons you really want to use one of those instead of Eldritch Blast.
