Iterate over objects and print select values - json

Question

Question: I would like to know how I can iterate over an object to print out the name of each subnet and its cidr range in the subnets object.
I know how I can print out the vnet name and cidr range:
jq '.[] | select(.vnet) | {name: .vnet.name, cidr: .vnet.address_space[0]}'
I have looked online and found that you can convert the object to an array, but I am unsure how I can look through that array to print out the values:
jq '.[] | to_entries | map_values(.value)'
Essentially the desired OUTPUT should look something like this:
{
"name": "asdf1",
"cidr": "10....."
},
{
"name": "asdf2",
"cidr": "10....."
}
//...and so forth

Start with the root path and traverse down and use to_entries to get past the varying key names and use the .value field only
jq '.vnet_spoke_object.subnets | to_entries[].value | { name, cidr }'
or collect it as an array of objects
jq '.vnet_spoke_object.subnets | to_entries | map(.value | { name, cidr })'
