I've got a '23 Legacy Touring XT and got this EcoHitch Hidden Trailer Hitch Receiver installed at a local shop recently: https://www.etrailer.com/Trailer-Hitch/Subaru/Legacy/2023/EH36RR.html?VehicleID=20236004107
It doesn't have any clearance issues since from the side it doesn't hang down any. Would that work for you?
(I too use it for a bike rack)
