I’d like to think that it is an unspoken rule among all spacefaring people, regardless of their planetary origin or biological design, to automatically reorient their ships to match the “up” direction of any other ship they are approaching.
It makes sense since (effectively) all spacefaring peoples started on a planet with gravity and well defined “up” directions. You wouldn’t interact with anyone in gravity while upside down, so as a courtesy you’d always want to be facing “up” for both your sake’s.
Technically, this only needs to be the practice of Starfleet (or even just human) navigators in order to account for 99% of what we see in Star Trek. Maybe it’s our guys who are doing all the careful orienting, and the alien of the week just comes in from whatever angle they want.
