Along with everything else, the friendly relationship between Goldie and Jennifer is believable.
(I get so tired of the "first wife and second wife who hate each other" tradition.)
I'm afraid I've never really known her from them. The only one I can name is the Martin and Lewis comedy LIVING IT UP (with Grace Wheeler herself, Janet Leigh), and I think that that's one single scene.
It's funny that in one scene Goldie is dressed in something like a Broadway musical costume, which looks like some little reference to that.
Janis Paige was great as Goldie. She certainly had a good innings. The only Columbo guest star that I can think of who has lived longer than that is Nehemiah Persoff, who pla*** the murder victim Jesse Jerome in "Now You See Him" (1976). Born in August 1919, he died at the age of 102 in April 2022.
