I’m no electrician, I don’t run a lot of cable, I’m just a maybe-slightly-more-competent-than-average DIY homeowner type
Personally though, I like having cables run through conduits when possible for the ease of running them. I’m not particularly worried about water or mice or anything, it’s just a lot easier to just drop a cable down a pipe or suck a string through them with a plastic bag and shop vac than to try to fish them through the walls, especially anything I might want to upgrade at some point down the line when a new standard comes out like Ethernet or HDMI.
