Instead of using the UID, you can use the URI:
fields:
name:
label: Name
type: select
options: query
query:
fetch: pages
template: route
value: '{{uri}}'
Edit 1: Have a look at the list field. It generates the kind of output you are looking for.
Edit 2: Don’t know if you can use that together with querying pages, though. You could however adapt this field to your purposes.
Edit 3: If you can live with a comma separated list of entries, check out the multi-select field by @distantnative
