I am in the same boat as you, Titanium but most of my stays are at Marriott's lower tier properties. There is not much for the hotel to do. Late checkout whenever I want it (not often). Sometimes I get a goodie bag when I check in, on top of my welcome gift of points (Couple of bottles of water, candy or other snack). If there are bigger rooms, can often get into one (I like to ask a few hours before I arrive via chat on the app, seems to be the best success rate).
