>I assume there is no point in NOT using fast travel all the time
yep, correct
if you're modding there's a combination of mods that make overworld travel a thing tho. travel options + basic roads lets you automatically follow roads connecting towns with configurable gamespeed. combine it with realistic wagon, climates and calories and you've got a wagon durability as well as your own needs as an extra concern.
then there's world of daggerfall and encounter mods like warm ashes which add landmarks and random events along the roads and wilderness to interrupt your journey
