I thought your "Street" on the credenza was great ..

.. and probably best for those pieces .. otherwise, just shape some Styrofoam blocks to suit and spray paint .. the problem with these things is they are just a big hassle (but they look nice) ..
I never really knew of it before, but last Holiday Season, I discovered that a few folks had started up a "Christmas Decoration" business .. where you supply the stuff and a crew comes in and puts up all the outdoor material and does the inside as well if you're willing to pay for it .. kinda takes the "Griswold" out of the Holiday .. I don't know what they charge, but that's the modern World, I guess .. everything seems to eventually get a dedicated Business you can use to take care of your personal needs and do it through an App ..
Maids, Yard Work, Decorating for Holidays, Meals Ready to Cook by Mail, Personal Shoppers, Uber, etc .. used to, a pizza was about the only thing you could get delivered, now you've got GrubHub ..
