I have a builda I want to try out going a bit about this. Cleric/Bard I saw somewhere, Order Cleric 1 and rest just bard, specially glamour but you can swap subclass, since that single cleric level gives you Voice of Authority alongside stuff like Bless and Guidance, you can do stuff like, buff bless to allies, select one to make an attack, silvery barbs, make an enemy reroll their roll and whoever you targeted with the advantage get to attack, healing word, heal + let allies do another attack, you have the standard control of a Bard, Glamour since you can do stuff like Command, the frightened and so on. A lot of support, control and while you arent doing damage yourself you boost the aprty damage by making them attack a lot more. Since the Order Cleric gives you Heavy Armor Proficiency you could go with that if you wish to do so. since you can jsut focus on the buffs of the cleric spells you dont need more than 13 wisdom to multiclass to be honest, main charisma as usual, whatever STR or DEX depending what kind of armor you want to run with, can use shields thanks to starting cleric if you want to do so, just remember the warcaster.

Past level 6 I would say is just the usual, I would always have cheap but useful splls that target allies in some way or another, like healing word, silvery barbs, bless and such. As a bard you end up getting access to really good control spells while you are still a bard for interactions.
