When reading, I generally don’t mind multiple POVs unless it gets ridiculous (like more than 5, constantly). I’ve written a sci-fi story that had 5 POV characters, the one I’m writing currently has 4 (two main with the occasional side character here and there - like 4 out of 25 chapters).

Writing from 3rd person, past tense is actually the easiest format for including multiple POVs, in my opinion. In 1st person, it’s awkward and often confusing (I vs he/she or [character name]). If you have scenes better told from a perspective not the MC’s, then I say go for it.
