They changed True Strike significantly in the 2024 rules making it no longer a waste of an action for regular attacks.

New Strike lets you attack as part of the casting using your spellcasting stat in place of str/dex for the weapon, optionally changes the weapons damage type to radiant, and adds cantrip scaling to your weapon damage.

The one use case for original True Strike to give advantage on leveled spell attack rolls and reduce the chance of wasting a spell slot (or other consumable) on a miss is gone though.
