I think you might be describing analysis paralysis (https://en.wikipedia.org/wiki/Analysis_paralysis https://en.wikipedia.org/wiki/Analysis_paralysis). While I can't advise you how to deal with it I find that acknowledging the tendency makes it easier to override, particularly for relatively trivial and inconsequential decisions like your example. Years ago I used to aim for 100% "information coverage" to base a decision on. These days I'm slowly starting to realize that the diminishing returns past a certain percentage of "information coverage" are rarely worth the time, though this depends on the gravity of the decision. In the case of the make/brand of my phone case I'd visit a site like thewirecutter.com and order their top pick.
