Just to add I worked out the answer and most of the clues and the general theme an hour before the the User Sean 47 did he just touched up a certain errors here and there. I was only around the corner to tidy up the clues before he posted his answer.
Pretty sure the 10 lettered place is…
California
Because
The clues I have worked out point to cities in California in alphabetical order.
Before we start
The clue ‘on side’ points to the fact that the clues are on the right side of Santa to create a city. These are all the cities in California which start with “Santa”
Here are the clues and the cities in order:
The clues:
An actress in the latest Bond movie
This refers to the actress ANA DE ARMAS from the movie “No time to die”
A Bird of Prey
This refers to BARBARA GORDON from the DC Comic book Team: Birds of Prey
A Doctor's assistant (and someone that looked like a smaller version of them)
CLARA OSWALD - one of the more recent assistants of Doctor Who 11th and 12th in the British Sci-fi series Doctor Who.
A Beckham

A pile of metal bits from a mattress (I don't know what I was thinking there...),
SPRINGS
A von Trapp
This refers to MARIA VON TRAPP from the Sound of Music
A Friend

PAULA ABDUL
