The only place STR accessories are actually a thing is raids. If you choose to use VIT in whatever other content you're doing, it really doesn't matter. You'd have to be extremely picky to care that your tank is full VIT in a 4man dungeon, for example.

If you can afford pentamelds, those are pretty universal in and out of raids, but they're also heavily not worth the gil if you're not raiding at all.
