Your score should ideally contain all of the information necessary for a professional musician to sightread the piece properly on the first try. By "properly," we just mean that they understand the basic techniques they need to execute to convey the idea of what you want. If you don't care what they do, then don't include markings! And to the contrary, there is always room for more nuanced interpretation with further rehearsal time. A crescendo means get louder, but doesn't necessarily say how loud or at what rate. A conductor can help communicate this (even when sightreading), as can feedback from the composer.
So to expand on the first point, your score is communication with the musicians. It tells them what they need to know. If you're writing a jazz chart, the musicians will automatically interpret certain rhythmic gestures with certain articulations -- this is true for any idiomatic music that fits into a well-known style. When you're making use of an idiomatic musical gesture, you may not need to include all the markings for a literal interpretation, but you should include markings that the musicians would expect to see, based on the rest of the published repertoire in the idiom.
In contrast, many composers are expressly focused on crafting a new style that doesn't fit into any existing idioms. This often means more ink on the score is used for markings than it is for noteheads! But if you find your digital entry of interpretive marks to be tedious, I would suggest that you may be missing some software usage patterns that could make your job easier. You shouldn't need to duplicate your efforts for music that is marked the same way in multiple staffs or multiple places--whenever I find myself doing this in Sibelius, I go looking for a shortcut or plugin, since something usually exists that I've been missing. (And if it's still bugging you, once you get rich and famous you can hire someone to typeset your scores for you!)
