If your question is more about raise sizing for position regardless of your cards, then it depends on your approach and your table.
Some advocate the same raise for every position, at a positionally aware table some raise less; 2 1/2 BBs from early and more, 3 1/2 to 4 from late. If the table isn't positionally aware, then 3 or 4 all the way around.
And then it depends on the standards for your table. If people tend to call 4X but fold to 6X, maybe 6X should be your standard for that session.
Edit: as for 3x for a late position steal, yeah I'd open in late for 4x. But it really depends on your table/level too.
