>>106092495>brave://settings/shields/filtersTLDR: Solved. Thanks anon.
Long version:
Not sure what happened but I had uBlock origin installed on top since it came clutch in an edge case years ago. Removed that, did some refreshes, droped shields, cleared history, messed with the experimental stuff on the list you mentioned, set it to aggressive, shields back up, now working.
Seriously. Whoever is not on this browser yet? Good. Stay away. As long as its is the minority of the market share it means those using it get to live in the minority and have an add-free life.
