What is the best practice for passing a filter from a record in a record type list to the record dashboard?

What is the best practice for passing a filter from a record in a record type list to the record dashboard? We only want to show data in the record dashboard that meets filter criteria from the selected record, understanding that data in the dashboard UI can originate from other sources besides the record type, i.e. record type field = "A" and we want to pass "A" as a filter into other expressions that query other tables of relevant information. Do we simply insert this SAIL expression in the query expression, or is there some guidance elsewhere that will tell us what to do?:

queryrecord(
recordtype: some constant
query( type!Query(
'logicalExpression|filter|search': type!QueryFilter(
field: the dot notation of the other non record type field to apply the filter (looking for "A")
operator:=
value: the name of the record type field to use as the filter...what's the syntax

thanks...
