. I would go for the via-in-pad with plugged via. You can see where the Rounded Rectangle pad shape passes DRC clearance checks. Cap the via-in-pad with surface finish, planerize flat

. I always "Flood Over" every via in a PCB layout expect those that are via-in-pad will have a thermal relief. The via-in-pad vias have to be specially marked on the fabrication drawing as they need to be plated, plugged, capped, surface finish and planerized flat so that you cannot tell if there is a hole or not
