Newly refinished floors are going to draw attention to the mismatched base trim. It all needs to match.

I hate shoe moulding & am willing to scribe trim to the floor to avoid it. Others, however, don't mind it. The important thing is to have consistent base.

I’d probably do the same as ci — use the money to match up all the existing base rather than adding shoe to all the mismatched bits. I particularly like the taller molding with the ogee piece on top of it in the far back wall portion of your first photo (and looks like there’s some in the second photo too?).

Thanks, I’ve decided not to do the shoe molding. I’m also not going to update/replace the moulding. It’s never bothered me, and, with furniture in place it’s hardly noticeable. Appreciate all of your help in guiding me toward the decision that is right for me.

Enjoy your amazing old floors, bet they turn out gorgeously!

Good decision. People tend to obsess somewhat over details that most people will never notice. You can always go back and add shoemold in the future. IMO, when it's painted to match the baseboard you hardly notice it's there. I had a client who objected to it being used when we installed new wood in her breakfast. Evidently she never noticed that she already had it in the rest of her house.

Agree you can always add it. I would look carefully at the edges of the refinished flooring, on ours, there are some ghost remnants of paint and nail holes from carpet tack, and it looks much better to just have a clean shoe molding installed.
