Stick with a quality 0W-20 oil. I'd go 3000-3500 miles oil change intervals. These new Subarus with direct injection have very high fuel dilution. For comparison I have a 2021 outback with 2.5 non turbo engine. I ran 4800-5000 miles using Amsoil signature which is a one of the best oils out there. That oil took a beating. Over 5% dilution. Anybody recommending 6k mile oil changes on Subaru DI especially turbo is nuts. Just to solidify my point. Look up any post 2019 2.5 or 2.4 Subaru oil report and all of them have sky high dilution. I recommend you stick with oem, wix, or amsoil filters only. As they have the correct oil bypass rating.
