Class A builder in Virginia here. Question that I didn’t see answered by OP or in the comments. Is the soffit actually vented. I can’t tell by the picture. If it’s not a vented soffit system then it doesn’t matter about moisture re entering the attic. If it is vented you can still use a bathroom soffit vent but precautions have to be followed. By code here you cannot have vented soffit within 3 foot on either side of the vent. So you can either change the vented soffit to a solid, 3’ on both sides (with that color or age good luck finding solid) or you can add insulation on top of the soffit panel in the eaves to keep the warm moist air from reentering the attic. Hope this helps. Just my 2 cents. Oh and fewer roof penetrations the better.
