Ways to heal after casting a spell as an action in the same round



Context

Following this question, I am looking for ways to heal in the same round after casting Beacon of Hope from a Ring of Spell Storing.

I was looking for an abilty like a Divine Channel or an item I could use to heal but didn’t find anything. (and I don’t really know where to search besides Google and the Stackexchange)

Sidenote: I am a level 5 cleric of Qotal but I’m also interested to know how other classes could do.
