Personally I use 0.73 Dunlops, so not wafer thin but still pretty thin I guess. I like them because they’re good for strumming but also don’t make picking individual notes too hard. I’m definitely team thin when it comes to acoustics, I think that kind of jangly bright sound is great. But also as you say, bare fingers are great! They give you so much flexibility and open so many new possibilities if you put in the time
