centiMorgan distribution among human chromosomes
The short answer is "yes". Here is an early example: https://science.sciencemag.org/content/265/5181/2049.abstract

I am sure that with some searching around you can find the most recent version. I was able to find somewhat more recent maps here. The data has to be in the UCSC genome browser somewhere. Most likely you should find your 7000 cM estimate source and figure out which map that estimate comes from if you like that source.

These data structures are called "genetic maps" or "linkage maps". Each chromosome has positions that are defined by cM, and you could use that for your purpose I believe by just taking the largest cM value marker for each chromosome.

(Note that the two copies of a chromosome do not have independent genetic maps- after all, the map is defined by recombination between the two homologs. e.g. for chromosome 1 there is usually just one map, and therefore one maximum cM value- the map is an average across the human chromosomes sampled.)

Edit
The question seems to be related to a genealogical heuristic for identifying relatedness in cM values. I'm still not 100% sure how they measure this exactly.

The source shares expected values for relatedness here: https://secureservercdn.net/184.168.47.225/35b.ded.myftpupload.com/wp-content/uploads/2018/12/Relationship_Chart_FINAL_August_2017.jpg
