That's a good point. If your focus is not on spellcasting, it's a decent multi-class, particularly as Cleric gives you medium armor and shield proficiency. In that case, I'd suggest Rogue at level 1, build up to Rogue 3/Cleric 3, then with most of your further levels in Rogue.
War domain allows you to make an attack as a bonus action, a number of times equal to your Wisdom modifier, recovering on a short or long rest, which is worthwhile if you want to fight with weapon-and-shield, or cast a spell as mentioned above.
You can get True Strike if you take the Arcane Trickster archetype for Rogue. Or if your DM is using the 2024 Player's Handbook and allows domains from earlier publications, you can get the True Strike spell with the Arcana domain for Cleric. Booming Blade and Green Flame Blade cantrips also work well for a melee Rogue.
There's some advantage to taking the Arcane Trickster archetype for Rogue, as it continues your spellcasting progression, albeit slowly as it is your Rogue level/3 round down. For example, at Rogue 15/Cleric 3, you'd have the spell slots corresponding to a level 8 full spellcaster, but your highest spell level would be only 4th from Arcane Trickster and 2nd from Cleric - so you can pump up spells with higher level spell slots, but you won't have access to higher level spells.
